During the preview stream for the Riviera Line, Tyler talked quite extensively about Automatic Train Protection implementation on the Class 802. As is the case in real life, ATP does not operate in full supervision mode down on this part of the line, but still has partial supervision. The way this works was nicely explained in this part of the stream. The existence of ATP in game isn't particularly obvious and there also doesn't appear to be any documentation around it so I've attached a quick rundown of how it works in TSW. Rollback protection is also included. It is very cool to have this in game, but there are a couple of issues present that could do with being addressed: There is no audible alert. ATP has it's own alarm system that I can only describe as obnoxiously noticeable. For some reason this is absent from the game. The lack of target speed indication. There are green LEDs that denote 5mph increments around the speedometer. These should be illuminated at 125mph in normal operation and 20mph when in shunt.* Exiting shunt mode seems to be incorrect. This should be done by pressing the "On" button, however, it is currently done by pressing "Brakes".* Finally, as Class 80X's are limited to 124mph (126 in game for some reason) you will basically never trip partial supervision, so the feature ends up being almost entirely missable. Hopefully we'll be able to see some of the issues rectified and maybe even the full version of this safety system in place in a future route. *These two points might be incorrect, I'm going by what I could find online which is rather limited so feel free to correct me.
Yeah, it isn't perfect, but I'm glad to see it in part at least. Really wish that ATP's iconic alarm was included though. Also, although the 80Xs are limited to 126 in game, that only cuts the throttle and on any hill, you can get over that. So of course, I did the obvious and sent it full speed down the lickey and triggered it. Was fun, but a little underwhelming without ATP blaring out at me - I guess the only thing I could compare it to would be triggering PZB without it doing "Zwangbremsung" or any other sound at you 100 times lol. Would've been cool if full supervision was added to GWE too, but understandably given it's a project in Liam's free time, that's not planned.
Thanks for the info. I was wondering what it was. I noticed when I turn it on I get an "ATP" icon on the HUD speedometer (the game HUD) but other than that it doesn't seem to behave any different from AWS from what I was noticing. Is ATP something only present in the GWR 80x? I never noticed or heard of it on the ECML 801 - not sure if that is how real life works or just not modelled in game?
ATP only exists from Paddington to Bristol and Marylebone to Banbury (?) so the LNER examples have no use for it.
The ATP seems to also has rollback protection at neutral. This can be replicated when you change the reverser to neutral at speed.
Yeah the Azuma's don't have ATP installed since they don't use it, so for the GWR 802 the cab needed to be slightly different as the Azuma just has a plus socket there instead. In fact I was able to get into a TPE 802 cab at Lime St last year (802213) and I noticed there's actually nothing in that part of the cab, it's just a plain black panel there instead. Quite interesting to see how the 80x trains vary slightly with different classes and subclasses.
