Been playing with 390 and love it but have a few questions. So with tass the light comes on only when enhanced permissable speed is available to go up to? The balises trackside measure this? What determines when that speed supervised light goes out. Also how do you use hill start and speed set If you were at max permissable speed say 40 would tass still beep at you if you went over by a certain amount. What is difference between Eps and max permissable? Is eps just tilting? Why does tass light stay on even though there is a speed reduction to say 40 from 125.
Hi Samuel, The hill start, you just have to press on top of the lever, the "ball" is spring loaded on the handle. It ensures there is a braking application until you apply power. To activate the speed set, you just have to click on it as you're approaching the desired speed (say 124 for 125mph). But I don't know if it's working by 5 or 10mph increments. When it's on, you can change the notch, but selecting 0 will desactivate the device (don't know if it's true to life, because that imply to reactivate the thing after passing a neutral section). EPS means Enhanced Permissible Speed. It's a speed limit that only apply to certain categories. On the WCMLS, that applies to tilting trains, but it's not the same for every tilting trains (Pendolino vs Voyagers) and sadly, the game makes no difference. Some British experts will be able to explain this to you better than me (example : are those MU signs considered as EPS ?). So the EPS of 125 is the maximum permissable for the Class 390.
"MU" written on a speed board is separate to EPS. "MU" stands for Multiple Unit, and thus applies to every Multiple Unit. EPS is for tilting trains where tilt is enabled, so only Pendolino's now. Cross Country disabled the tilt on their Super Voyager sets, and Avanti replaced all their Super Voyagers with non-tilting Class 805 and 807 "Evero" sets.
Absolutely "every" or just those that do regular services on those routes concerned ? I was wondering about the HST on the WHL in particular, but maybe it's not considered strictly as a MU...
The TASS does not really work properly. I made a thread about this a while back... https://forums.dovetailgames.com/th...olino-tass-speeds-and-tilt-disablement.94687/
When passing a neutral section on a modern day unit like the 390 you don’t need to go back to neutral. The train will drop power by the resistors dropping out then apply power again when out a neutral section automatically. It’s not like a class 86/87 when you need to run down the amps to 0 before getting to a neutral section then applying power when the light comes back on as it don’t drop the overload out on a 390 like the 86/87 etc
I was wondering about that because even if two pieces of rolling stock belong to the same category (for example, MU), their physical characteristics (weight, length, etc) can be so different that they won't be allowed to run at the same speed in the same places : This is the case on the curves at Berkhamsted and Leighton Buzzard : 115mph for the tilting Voyagers, 125 for the Pendolinos (thanks to a forum member named arcsin for the information). So I suppose there are restrictions specific to certain types of rolling stock, and that these signs are just general guidelines that aren't sufficient. You can't just say "an MU is an MU, let's go at those higher speeds". For specific cases, you have to go into details, which real life drivers of course know, but that we players aren't aware of. And I think it's a step toward more realism to let us know such things. Example : ok it's a passenger train, but that Bo-Bo Class 67 is so heavy that you are not allowed to cross that bridge at the speed the board is showing... JT in particular has done a great job in making the speed limit on the HUD corresponding to the one applying to the train you are actually driving (for example 100mph for the Class 86 where it's 110 for a 87). It's a step in a good direction and I hope we'll see further improvements as such !
That's also a fair point. On the Edinburgh to Glasgow route there are SP boards for Sprinters (15x) only. I also believe the Class 185 is sometimes subject to lower limits because it's weight, of course there's not one in tsw though. Speeds are complicated
Yes JT are leading the way here, not surprisingly. Even a couple of times where I thought they made a mistake, only to check online info and find that they were in fact spot on. On the flip side, you get the odd freight limits on BCC and BML etc, which kill a lot of the enjoyment for me.
To be fair, I was pleased to grab a 87 on the WCMLS and not having the HUD showing 125 as maximum permitted. In TSC you needed great route knowledge if you wanted to do it clean. And, my God, I'm not talking of the Caledonian Sleeper on the WHL... I may be quite finical, but I like to have mistakes such as overspeeding reported at the end of the journey. That thing with the spring loaded notch lever on the Class 87 ? Man I was so glad they were right. I would have been devastated if we had regressed compared to TSC. Alas the same here.
No, that is not quite right I don't think, but I can live with that. It was more about all the different speed limits they have set up for the various locos in various configs, running light loco etc, etc...
That's right. In fact, a Pendolino cannot run at MU or EMU speeds. The letters on speed boards apply to the following classes (From the sectional appendix for London North Western (South), page 9): HST: Class 91 locomotives with mark 4 vehicles and DVT, classes 158, 159, 168, 170, 171, 172, 175, 180, 220, 221, 222, 253, 254 and 373 MU: Multiple Unit Trains DMU: Diesel Multiple Units EMU: Electrical Multiple Units SP: Classes 150, 153, 155, 156, 158, 159, 165, 166, 168, 170, 171 and 172 CS: Class 67 With a note that Class 390 trains cannot run at MU or EMU speeds and class 185 trains cannot run at MU or DMU speeds. You can download the sectional appendices here: https://www.networkrail.co.uk/indus...ators/national-electronic-sectional-appendix/ That list might be different for different regions (I haven't checked) but the 390 and 185 restrictions are national restrictions.
Thank you mate for another helpful and interesting post. I was about to contact you a few weeks ago in order to get informations from this sectional appendice as I didn't suspect it could be directly available online. I was planning to form a railtour scenario with a HST on the WCML in TSC, and precise knowledge of speed limits was needed. But at the end TSC was quickly uninstalled instead, and now I'm enjoying TSW !
This suggests they were reclassified to run at MU speeds, but handbook not updated. No idea myself if that is true or not, but was stated with some confidence on there.... https://www.railforums.co.uk/threads/class-390s-without-tass.261353/
