    Does anyone else find the Class 166 accelerates like a crazy rocket from 0-30mph? I've been on a lot and yes they are brisk off the line, but it feels like a family car type acceleration rather than a DMU. From 30mph onwards it seems to be slightly more true to life. Just needs to be toned down a fraction. Not too much, just 10-15%

    There also needs to be more of a delay between the revving up (to fill the torque converter etc) and the actual pull away movement. Should be around 2 seconds I believe. I feel the HST lacks this too. 1-2 second delay from throttle movement to the amps actually starting to rise.

    According to real world timings it should be hitting 40mph around half a mile.... Even starting in notch 4, then working to notch 7 after 5-10mph it still reaches 40mph in half that. 400 yards or less.

    I really just don’t understand how anyone with a shred of knowledge can let that slip through the design stage, let alone testing.

    Look at the graph. The graph speaks for itself. 0-40mph in approx half a mile - not 1/8th

    It is data recorded running out of Slough heading towards Reading which is how I tested it in the game
    Way out

    I have just done some more testing and timed runs. The 0-20mph time is 10 seconds, should be theoretical 11 secs at the very quickest. More like 13-14 in average unit with passengers, worn engines etc.

    0-90mph was 3m57... again 3 seconds off the very very minimum and quickest time. Should be AT LEAST 4 minutes, but as I said, the average units will take (from my own real life timings) around 4m30 (level track)

    Everything in this game feels so ‘autistic’ By this I mean so literal, clean and extreme / clinical, it’s not close to real life. Brake pads wear and fade, They don’t always bite so viciously like they do in the game. It is such a shame because with Armstrong Powerhouse’s physics, they are so so much more true to life. I have done so many real life data and speed timings on their products and they are always bang on. Time after time.

    DTG on the other hand....visually incredible models... physics...much more work needed. These are the same guys that released a Class 150/1 in TS that sprinted from 0-60 in less time than a flipping Ferrari. Utterly absurd. Yes this is slightly better but it still needs A LOT more attention to acceleration and braking characteristics.

    This is why, once again I’ll say we need a decent physics editor so we can adjust this kind of stuff ourselves rather than .... at best, waiting 6 months for a fix, or at worst, the team ignoring it all together.

    In fact - I am confident that if anyone can get some real life class 166 or 165 GPS videos and recordings ( upload them to YouTube and post me the link on here ) of less than 11 seconds 0-20mph or 0-90mph in less than 4 minutes on any level track ( GW main line for example ) then I will personally PayPal you £100. GPS on your phone, video it with your iPad - Go.

    I see no one has been able to manage to claim that £100 yet then? hahaha definitely accelerates too fast

    Might be because people are following lockdown rules that no one has provided data.....

    While the 166 is quick of the marks, it used to be completely the opposite. The new diesel traction physics greatly improved its time keeping.

    For a 3 car set with 1050hp from the 3 x 350hp 14 litre engines, I'd say its pretty well represented (if you've driven or been a passenger on one you'd know)

    While I admire your data analysis, there's a lot of room for error in your calculations etc, railhead conditions etc which are replicated in the game engine, yet you haven't mentioned what your test environment was.

    You're asking for train operator levels of physics in what is meant to be a recreational GAME. If DTG did replicate full on physics, the trains would be undriveable to 75% of the player base.

    Think you need to step away from Train Sim World if you want the level of realism you seek and go and either a.) Become a train driver or b.) Look for something developed for FOC/TOCs that would cost you upwards of £10000 for a licence.

    The op made another thread on the 166 yesterday, I replied to him on there :)
    https://forums.dovetailgames.com/threads/class-166.35042/#post-246072

    I had a second go on the turbo (Class 166) today and it does feel driving an EMU, it’s extremely quick at least for the first 20mph or so. Having said that, I wouldn’t say the turbo is unplayable or ruins the experience that much to be honest. Perhaps only use Notch 6 maximum if you want more authentic acceleration?

    Regarding delay about revving/amps building up, yes I would agree with that. But again, I wouldn’t say it ruins the experience. In TSW, the HST was very disappointing with the instantaneous brake response and unable to take power without releasing brakes fully. Both of these were in my opinion critical faults and make the HST unplayable. But in TSW 2, I have been very impressed with the HST as both of these critical faults have been fixed. Yes, there are minor things that need fixing and I could go on a whole list. E.g. when parking brake is applied, brake pipe should be vented which isn’t in the game but I can overlook these small details. Similarly with the turbo, it was unplayable in TSW because of the sounds (or the lack thereof!). But in TSW 2, the sounds have been fixed and the turbo has generally been enjoyable to play now. Like Bryer says, you can’t expect perfection. I am quite happy with both traction now.

    Well I have reported it to DTG and they have come back and acknowledged the error and will look into it.
