    Is the preview stream going to show progress on the remaster alongside the new Rivet timetable/locos or are we just going to see the new timetable/locos?

    Will the sound improvments for the SR 170 be backdated at launch or is this is a planed post release update to the Fife 170?

    Thankyou

    "since the timetable is set in 2017-2018, we are including the two-car 171/7 and the four-car 171/8 exclusively as part of this Add-on"
    From the article.

    Again, re the 170 Fife sounds. Can we have an assurance this will be backdated before or when the pack releases and not just kicked down the road again?

    Why did Rivet pick the low hanging fruit with the all too common TSW tendency to recycle an existing train and squeeze more money out of it, rather than bringing something new? A Thumper DEMU alongside a 4 CIG (BIG) with a retro timetable would have sold like hot cakes. As it is, hot on the heels of the 805, we are being asked to pay £13 for another glorified reskin.

    Do you need to buy the pack to get both new timetables, or are they included in the remaster?

    I'm very pleased with the news that all rolling stock on the route will receive new features. Can we hope that after the Class 313 gets the suspension feature, the Class 314 on the Cathcart Circle Line will also receive this upgrade?

    The main question from me is regarding the Fife Circle and BCC 170s, will the improvements to the Class 171 also be available to the aforementioned trains on launch or in future update?

    - Regarding layers from the DTG article, why is the Class 377/2 (from WCML South) not included? While obviously it has a pantograph, the /2s are still used across the whole Southern network coupled with /1 and /4s. It would just add a bit more variety and realism overall.

    - Why choose to do the Class 377/3 instead of the /1, especially considering we already have the 313? In my opinion, having a proper /1 would've been better overall and could be used for other routes like BML etc.

    Are there 2 new ones? I believe 1 new with the class 170/377 and 1 old one with the class 313.... Or i'm wrong?

    You have default and 313 timetable with the base route, those would stay the same.
    With the gameplay pack you get two new timetables, one with class 377/3 doing Seaford services and one with 313 doing them, same timetables apart from that, so kinda like what happened with default timetable.

    Has the original ECW 377 been updated so it has the same standards as the BML 377? (For example, has the PIS screens, sounds, physics been updated to match?)

    And one cheeky question, although not important to the DLC... Will the 171 have a place on the BML timetable for ECS runs upto Selhurst? (Not important but more of a curiosity)

    They are not new trains though, just rework/reskins of ones already in game.

    Have you fixed the speed restriction at the top of the Seaford Branch where there is a speed reduction warning panel but no actual speed restriction?

    Will there be any 313 services at all in the 377/3 timetable and vice versa?

    And though it's technically a different train. The 805 was essentially a reskin too. Yes there were improvements, but there are also improvements with these aswell

    Just finished watching the stream, but didn't look like the 387 was used for any normal services between Brighton and Eastbourne. While the timetable is 2018, 387s have been quite common on the ECW in more recent years so would have been nice to see some extra variety regardless. So, my question, why can't you substitute the 387 for some of the 377 services?

    I’m thinking this is just more a lack of knowledge than much else. Really appreciate what Tyler has done for routes so far, really transformed how BCC plays & the sort of route it is, it’s looking the same for ECW too. I do think though, that a little more research here would have helped.

    It's probably technically ready for release, they just want to make sure they can launch on all platforms simultaneously. Especially since they want the remaster of the route and the DLC pack to release on the same day.

    I don't think they're waiting for the GWR Class 387 pack, it was only *just* announced (partially).

    Not sure on this one, but doesn't "player only, not AI" mean essentially "free roam spawn"?

    No, means you can select to use it but it won't be seen as AI similar to how you can choose to use the 465 instead of the 375 on the upcoming Medway Valley line but it won't be seen as AI

    I believe the 387s only came onto the southern service once/as the 313s were retired (2023ish?) as Southern didn't have enough stock to replace the 313s they got rid of so ended up borrowing some from GX. I certainly can't recall seeing them on Southern ECW or WCW services that early. Although I did manage a few coincidental trips on a GWE 158 into Brighton a few times before that was axed. :D

    Although I know Tyler said some of the 700 services divert through Lewes early in the morning simulating late running work on BML so maybe the 387 does some of those?

    But that's just GX 387 that we already have, I doubt that the 387 pack will give us another one, more likely is that there will be some ex-GN SN 387s that they got. It is unsuitable for the era, thus not substituting for AI services, while allowing players to use it to get more value out of the pack.

    Yes, while 387s have been quite common on the ECW in more recent years, personally I'd be happy to have them as more gameplay variety in favour of a slightly less realistic timetable to "represent" more of a wider time period if that makes sense. Anyway, having the specific 377/3 timetable set in 2018 doesn't really make sense either because it was only the 313 then - isn't it ironic that the 313 replaced the 377/3 in 2010 for East Coastway etc only to be replaced by the same units that it replaced thirteen years later! :D

    Perhaps too much work, but I think maybe Rivet missed an opportunity with the two timetables. Have the 313 timetable as the regular, and the 377/3 as a 'more modern' example featuring 387s etc - obviously, the latter timetable wouldn't have the 171 though, only going as far as Eastbourne nowadays.

    Completely agree. I do think perhaps there was maybe a missed opportunity with having the two timetables in bolstering gameplay variety to represent a larger time period. You could have the 313 timetable (if you own that DLC of course) which would also feature the 171 to Brighton. But, then have the 377/3 timetable as "more modern" featuring 387s etc - obviously, the latter timetable wouldn't have the 171 though except as AI, only going as far as Eastbourne nowadays. Obviously, the elephant in the room with the 377/3 timetable being 2018 - which doesn't make much sense anyway considering the 377/3s to Seaford etc would either have to be pre-2010 or post-2023.

    But yes, echo your comments and very much appreciate Tyler's work - long may that continue. Just to add, I'm certainly not criticising, just constructive discussion and debate.

    Yes I mentioned the 377/3 ironically being the odd one out in the new TT, despite it being the paid add in.

    It’s funny for me as I would take a Turbostar any day over the Electrostars, but if I do use the latter it would be a 387. I think a good compromise here would have been to make the 387 a player only sub for the 377’s - similar to what Liam will offer with the GWR version (though even that is going to be on the handful of diverted 387 runs).

    Morning folks!

    I have the answered questions here from the livestream, along with some extras that Tyler has been able to answer.

    Will the AI Class 700s be extended to 12 car formations?
    No, both playable and AI Class 700 services use the 8-car RLU formations.


    Regarding the Fife Circle and BCC 170s, will the improvements to the Class 171 also be available to the aforementioned trains on launch or in future update?
    They will be in a future update.


    Can we hope that after the Class 313 gets the suspension feature, the Class 314 on the Cathcart Circle Line will also receive this upgrade?
    We at Rivet have no plans to work on the Class 314.


    Do you need to buy the pack to get both new timetables, or are they included in the remaster?
    The new timetables are only included with the Class 171 DLC.


    How does guard mode work on the Electrostars and can we see it in action?
    Yes, it’s on the livestream.


    What trains on the ECW Remaster have announcements on board?
    171, 377/3, 377/4, 313

    Timetable FAQs from Tyler
    Why 2017-2018?

    Most importantly, 2018 was the last year the Class 171 routinely ran all the way to Brighton;
    afterwards they were cut back to Eastbourne. This set the end date to consider.

    As for the start date, the Class 700 was still entering service in 2018, and I wanted to include it
    as AI at Brighton. Also in 2018, Thameslink was running mileage accumulation trips between
    Three Bridges Depot and Eastbourne which are playable between Lewes and Eastbourne.

    What service does the 171 operate?
    The Class 171 operates diesel services over the Marshlink line between Ore and Ashford
    International, connecting to Brighton. These stop only at Polegate and Lewes, except for the
    first service of the day which makes additional stops between Lewes and Brighton.

    What services do the 377/3 and 313 operate?
    There are two timetables, one with the 377/3 and the other with the 313. In each, they handle
    trains on the Seaford branch and the shuttle between Brighton and Lewes. As per the WTT, one
    service also runs to Eastbourne and back with a layover at Eastbourne Yard.

    Why make the 377/3?
    This project started two years ago as a free mod, the first thing I ever made for TSW. It's a
    replica of the December 2017-May 2018 Working Timetable, during which time the Seaford
    branch and Lewes shuttle services were almost exclusively operated by the Class 313.

    When we decided to adapt this timetable for the Class 171, we realised that players who don't
    own the 313 would be missing about half the services on the route. We didn't want to make a
    train DLC that needed a second train DLC to feel even close to accurate.

    ● If we step back before 2010 when the Class 313 entered service on the East Coastway,
    the signaling on the route is too new and Brighton loses its Gatwick Express and
    Thameslink AI.
    ● If we move forward to 2023 when the Class 313 was retired, the Class 171 no longer
    runs to Brighton, just Ashford to Eastbourne.
    Both before and after the Class 313's time on the Coastway, the 377/3 was a staple on the line.
    We decided to play with our time machine a bit and also provide this train in a separate
    timetable from the 313. Everyone gets full gameplay on the route, while if you also own the 313
    you can play that separate timetable for full accuracy.

    Can I substitute the East Coastway 377/4 for another version?
    When selecting a Class 377/4 service from the menu, you can choose the East Coastway or
    Brighton Main Line version, which has different sounds. The 377/2 from West Coast Main Line:
    London Euston - Milton Keynes can also be selected for any 377/4 service.

    Can I drive a Class 66?
    The aggregate trains from the original timetable are included, of course, and the Railhead
    Treatment Train makes a full working of the route including the Seaford branch.

    Are there any railtours?
    ● The Regency Javelin railtour takes a Southeastern 395 from Brighton to Eastbourne.
    ● The Buffer Puffer railtour takes top-and-tail Class 20s from Eastbourne to Brighton.
    ● The Flying Scotsman railtour has its namesake loco plus a Class 33, and runs from
    Lewes to Newhaven Marine, then back to Brighton (with the 33 leading), then to
    Eastbourne

    What unusual workings are included?
    All special workings are seasonal and are based on photos or videos from within a few years of
    the year the timetable is set.
    ● Thameslink Class 700 mileage accumulation runs, playable between Lewes and
    Eastbourne.
    ● An overnight engineering possession has run late and the first few Thameslink and
    Gatwick Express services of the morning must run via Lewes, and are playable between
    there and Brighton.
    ● A Gatwick Express Class 387 makes a special run to handle football traffic from Falmer,
    running empty from Lovers Walk Depot in Brighton to Newhaven Marine to reverse and
    then heading back to Falmer for boarding. (Today, Gatwick Express 387s are commonly
    used on the East Coastway substituting for Southern Class 377/4s, but that was not true
    in 2017-2018.)
    ● A driver training run takes a light engine from Brighton to Newhaven Marine, then back
    to Lewes. This uses the Class 37 from Tees Valley Line as in reality, but can be
    substituted for a variety of locos.
    ● A Rail Operations Group Class 37 hauls a failed Class 377/4 from Eastbourne Yard to
    Selhurst Depot for repairs.
    ● A pair of ECS Southeastern Class 375s detour around a landslip via Eastbourne and
    Lewes.

    Are any coupling/uncoupling operations modeled?
    The Class 377/3 mostly runs in a three-car formation but one is stabled as six cars overnight
    and gets uncoupled at Brighton. Another two formations join later in the day to form a six-car set
    for the afternoon rush and football traffic at Falmer stadium.

    The 377/4 has several uncoupling and coupling operations at Eastbourne where trains divide
    and join in the station to shuffle capacity around throughout the day.

    Finally, the Class 171 doesn't couple to anything (outside of a scenario, more on that below) but
    it does share a platform at Brighton with another train.

    Will I see many adverse signals?
    When this was a mod timetable, several community members requested integrating the
    signaling with level crossings. For example, driving from Eastbourne to Brighton you stop at
    Polegate on a red signal because the level crossing beyond the station is open. During your
    station stop, the level crossing is activated, clearing the signal once the barriers are lowered.
    This avoids excessively long waits for motorists and doesn't delay your train because you're
    stopping for the station anyway — but it does add interest for the driver, especially if playing with
    safety systems enabled.

    What Scenarios are included?
    1. Bridge Strike: A lorry is stuck under a railway bridge near Lewes. Drive from Brighton to
    Eastbourne and do your best to keep time despite the emergency speed restriction.
    2. Unit Drag: A Class 377 has failed at Berwick, and you're the nearest train. Take your
    Class 171 to drag it back to Brighton for repairs.
    3. Iced Over: Heavy sleet has iced over the third rail near Seaford. You're the driver of a
    Class 171 pressed into shuttle service between Lewes and Seaford.

    Are the existing East Coastway timetables updated?
    No, these are two new timetables which require owning the Class 171 DLC. The existing East
    Coastway and Class 313 timetables are unchanged.
