    Starting at the foothills of the Krkonoše mountains, taking in the incredible Jizera river and climbing the gradients before descending into Liberec - Czechia awaits in this all new adventure coming to TSW from the Vector Simulations team!

    Read our article on the DTL Website!

    [​IMG]

    We're thrilled to bring another new country to TSW players, and today we'll be covering some of the new features you can expect with the authentic Czech signalling you will discover as you play.

    Czechia Signalling Guide

    To start off, if you're familiar with Hl signals from Dresden Leipzig, then good news! You can expect Czech signalling to feel similar, with main signals consisting of up to 6 lights and having yellow and/or one or two green horizontal lights bars.

    Let's hand over the the Vector Simulations team for more information and details about how to operate the signals across the line:

    Vector Simulations: "LVZ and LS90 are both line safety systems, which means that they get informations about signals at any point through frequency modulated voltage in rails. This signal transmission system is equipped mostly only on electrified main lines and not present at the Liberec - Stará Paka (- Pardubice) route. As LS90 is a modernised version of LVZ (also called LS IV), they behave very similarly. If there isn’t any signal being transmitted, it works only as a vigilance control device, similar e.g. to SIFA. If there is any transmitted signal, it will adjust times between vigilance checks accordingly. Vigilance checks then start after the driver releases the direct brake, once the brake cylinders pressure drops under certain threshold (generally 1.5 - 1.8bar)."
    • Green code (only for Free signal) – vigilance is not required if the train is travelling under it’s construction speed. If in any case the train would exceed that, the safety system would require vigilance checks until the train slows down again.
    • Yellow code (Caution or Expect speed restriction) – vigilance is being checked if the train is travelling faster than 120 km/h
    • Yellow circle code (for any signal of speed reduction) – vigilance is being checked if the train is travelling faster than 40 km/h
    • Red code (Stop, Call On or Repeated Caution signals) – vigilance is required at all times
    [​IMG]

    VS: "Sometimes there can be some outside interferences present, e.g. high voltage powerlines running nearby the tracks, the safety systems can sometimes detect false signals. LVZ system was quite prone to this and player can see this in-game. LVZ equipped locomotives have also transmission frequency switch, where driver can select between 50 Hz and 75 Hz frequencies if a track-side signals say so. Newer safety systems do this switching automatically. 75 Hz frequency is used to eliminate most of powerline interferences, because even at a few hundred meters distance from the tracks they still can interfere if both powerline and code transmission frequencies are 50 Hz."

    [​IMG]

    "Distant signals then have only yellow and green lights. In some cases where visibility is limited or it is expected that a train would stop between the distant and main signal, there can also be placed a repeating distant signal. Those have the same lights as a distant signal, but have one more white light, which tells the drivers that this is an aspect of a repeating distant signal. Distant signals can also be integrated with main signals, e.g. in stations, where entry signal would work as a distant signal for the next signal, most of the times being the exit signal."

    Here are some of the signals players will most often see at the Liberec - Stará Paka route.
    [​IMG]

    • White light – shunting movements allowed, valid only for a shunting movement
    • Blue light – shunting movements forbidden, valid only for a shunting movement
    • Green light – free
    • Yellow light – caution
    • Red light – stop, also forbids any shunting movements past the signal
    • Slow flashing yellow light – expect speed restriction 40 km/h
    • Two yellow lights – speed restriction 40 km/h and caution
    For those unfamiliar with the two locos coming with the route, you can find the isolation switches for the safety systems in the engine room for the Class 750, and in the Class 843, the switches will be below to the right of the driver's seat.

    VS: "We have tried to maintain the highest levels of accuracy of the tracks itself, so players can expect to see accurate rail profiles with real curve radiuses, transition curves and gradients. We have created a completely new set of Czech infrastructure elements, including very detailed junctions."
    Thank you to the team at Vector Simulations for sharing these details, there will also be a detailed Liberec - Stará Paka manual on release that will aid players for the new signalling systems.

    [​IMG]

    We'll be exploring the timetable, scenarios and features in full detail in a new article coming out soon, but for now feel free to enjoy our gameplay showcase we revealed back in December for a better view of what to expect:

    Liberec - Stará Paka Gameplay Showcase


    Looking for more information?

    This route will represent the northwestern half of a single-track line connecting the regional capital city Liberec with an Eastern Bohemian conurbation of Hradec Králové and Pardubice, featuring a total of 11 stations and 9 stops, climbing and descending over 250-300 meters across a 75 km long run. You’ll also find 8 tunnels with overall length of 2421 meters and over 80 bridges of various sizes and lengths!

    This will be the first time I won't have to learn the signals and regulations. I'm really looking forward to this DLC. (Hopefully the texture issue will be fixed)

    Will the 750 feature an original audio set similar to Sulzer Type 2 or will it be the modernised muffled version?

    Will probably release either next Thursday March 5th or the following week Tuesday March 10th.

    It will be good to see another new country in the game, which is pleasing.

    That's what I was just thinking, and I would be really happy if that happens.

    In general, I'm looking forward to a new route in a new country.
    Finally something different again.

    Just stoked up the Steam Wallet in readiness. Assuming they don’t drop the ball and this has been rushed through QA, probably my most eagerly awaited of the tranche of new routes. Even more than Preston to Crewe.

    This route is an intriguing prospect, even though I'm not usually a fan of single track running.

    However, as with all DTG releases these days, 3P or home grown, I'll be reading the reviews from early adopters before hitting the buy button.

    Really quite looking forward to this, it’ll be the first time TSW gets a route in a country where I’m not at all familiar with the railway, it’s stock, systems or protocols.

    Diesel trains on single track, 50mph running & very twisty looking route, nice to get something different gameplay wise.

    looking forward to this one, and hoping it is successful, so we see some more modern Czech and Slovak routes and traction :)

    maybe one day:
    [​IMG]
    tho I would love to see the Slovak version that has increased max speed 160 kph :) ... but even this one would be awesome

    That's some pretty awkward information but I'll try to clear it up.

    For the signals, 5-light main signals are basically split in two parts where the bottom yellow is only used for showing speed restrictions while the top yellow, green and red show everything else. The two parts aren't really tied together so you can expect almost any combination of the top and bottom aspect.

    For the bottom light, a yellow glowing by itself means 40 km/h speed restriction valid from that signal. If there is some kind of indicator under it showing an aspect, it means speed restriction according to that indicator. An indicator can be a painted board with a white number on black background, glowing white number on black background or a a glowing stripe indicator.

    For stripe indicators, the rules are as follow:
    1 yellow stripe = 60km/h speed limit
    1 green stripe = 80km/h speed limit
    2 green stripes = 100km/h speed limit

    For the top part, the signal can show a still red, green or yellow just like what everyone is familiar with. If it's showing a flashing light, it means there is a speed restriction from the next signal. Flashing speeds are 54 or 108 flashes per minute, creating slow and fast flashing aspects.

    Flashing aspects are as follow:
    slow flashing yellow = expect 40km/h
    fast flashing yellow = expect 60km/h
    slow flashing green = expect 80km/h
    fast flashing green = expect 100km/h

    Note that if there is a speed restriction that doesn't fit these numbers like 50km/h, the pre-signal will always show lower speed that can be displayed. So for example a 50km/h speed restriction will have "expect 40km/h" on it's pre-signal. Only exception is 30km/h speed restriction that should have "expect 40km/h" on the pre-signal but I'm not sure if these still exist anywhere.

    Last but not least, a still white light displayed alongside a main-signal aspect means that the next signal is at a reduced distance (at least 50% of the regular distance). Signals that show this aspect also have an altered order of light where the white is in the middle instead of being 4th from the top. The white light is only shown if there is some kinds of restriction on the next signal, like a stop aspect or a speed restriction and isn't shown otherwise.

    As for the VZ train protection and switching between 50 and 75 Hz, it's not really done to avoid power-line interference as far as I know. Instead, it has to do with track circuits. They inject small amount of 50Hz AC voltage into the track to detect trains and to be able to tell between that and the coded informations, the informations have a 75Hz signal instead. This applies to all the lines with 3kV DC traction so the entire northern half of the country. For southern half with 25kV 50Hz AC traction, the track circuits are 75Hz and the information is (somehow) coded with 50Hz instead. Not sure how it would be on mainlines with no traction like everything around Liberec but I still don't think we will see the "VZ 5" signs.

    I actually got quite interested in Czech railways a few years ago after finding a few cab or “from the train” video clips on YT. There is or at least was quite a following from the UK as one of the bastions of loco haulage,in the same way that Greece and the Alco’s were a few years previously. Just a shame we are getting a 750 rather than the noiser 749 or 751 classes which sound very similar to our old Sulzer Type 2’s.

    Ok here's a fun signal installed in Ostrava-Svinov. Basically it has both a painted board and a stripe indicator. So if the bottom yellow is glowing and the stripe indicator is not, then the allowed speed is 50km/h (bottom yellow with a painted board showing a 5) but if the indicator is showing a yellow stripe, then the allowed speed is 60km/h (bottom yellow with a yellow stripe) and the board is ignored.

    Number boards with a glowing white 5 and a yellow stripe through the middle are made and it would serve the same purpose but I guess someone had a different idea.

    Sorry about a crappy photo but it's quite far from the platform for a phone pic.

    Even if the route is well made, I think perhaps the same mistake might be being made as with the Dutch route, by not starting with a route linking major cities like Prague and Plzen. Just a thought.

    No i think avoid Prague is a very smart decision! Big cities like that are problematic. Prague is the same size as Frankfurt and it will give big issues in consoles. Maybe in the future it will be possible but now with the console drama this is a well done decision is think.

    This is a unique single-track line that isn't even electrified yet, so diesel locomotives operate there. We have two such routes (the Niddertelbahn and the Maintalbahn). If I want to travel on yet another two-lane (or more) route between major cities, why would I need the Czech Route? I'll get exactly the same thing anywhere. And I'm unlikely to get diesel locomotives as traction, of which there are currently very few in the game.

    That's exactly it. And most importantly, it's different from the others. We have too many of the same routes, essentially. If they release another DLC with CD 770 - It's just a wish come true.

    Well maybe you're right, though you missed my point. We'll see if this route has longer legs than Niddertalbahn and Zwolle- Groningen.

    The fact that it's 45 miles and includes yard work and a freight component does give it more " oomph " than those other routes.

    I bought both of those routes, enjoyed them for a while, and I'm sure I'll pick this one up too if the early adopters like yourself recommend it. ( and the price is right ).

    However I doubt very much that Vector Simulations were thinking about console performance when they made their route choice.

    Disagree completely. Simply not realistic to think a first route from someone might include a major city. Let them cut their teeth on something manageable, then let them take that experience on to something bigger or more ambitious.

    MAC = Manchester is a copy from DTG
    Birmingham = The same copy from DTG

    Otherwise this discussion is useless.... We did not know how big the teams are and what their work effort could be.

    Mildmay is a single developer and isn't copied from another map tile as you point out the MAC and B2C are

    Edit: no, I guess the Gospel Oak station could technically be counted as "copied from DTG" under the same standard as applied to the MAC and B2C

    I want to be excited about this route, I really do. Especially since it's totally up my alley, being a single-track, not-too-modern diesel route through stunning landscape. And the snippets we've seen so far do indeed look breathtaking.

    But I've gathered enough experience with DTG at this point, that I think I'll join Crosstie and wait what reviews and the feedback thread will say about it first. It's not an in-house made route, I know... Nevertheless, looking at DTG's latest QA track record, I became incredibly cautious. :|
