Have played three activities in Railworks now, ummm... 166 Oxford to Reading, HST Paddington to Oxford, 86 Glasgae tae Motherwell. Played in Expert controls, with the silly HUD bar turned off, so no warning of upcoming signals, speed restrictions, or other stuff up ahead. The game does pretty well at letting you drive this way, with a combination of proper signage/signalling and route knowledge enabling you to drive to the timetable. You don't need the little track monitor window warning you how many miles it is to the next station, etc.
It doesn't really seem like that huge a step forward from MSTS or Trainz in 2001. The routes themselves look only slightly better than MSTS, while the 3D cabs with usable controls were in the very first edition of Trainz a decade ago.
It runs at a good framerate even with everything turned to maximum, which is nice. The only place it dropped below 30 (to 25) was in the very busy and detailed Glasgow Central station as I was looking around before I left.
Stuff I have noticed:
-freight trains don't carry a flashing taillight as they are meant to. IRL the train can't run without one fitted and operational.
-the combined throttle on trains like the 166 is annoying as you have no idea when you've got it at zero... there's no key to snap it there, and no real indication when you hold down the accelerate/decelerate buttons in expert controls.
-the activities are riddled with spelling mistakes and grammatical errors.
-the HST's horn sounds like a wasp trying to play a kazoo using its farts. The real horn
sounds the same as the other trains in-game.
-Airport Junction (where the Heathrow Express and Connect trains leave the main line and go towards Heathrow) simply isn't there... after Hayes and Harlington there's no huge flyover, no diverging line... the OHLE just suddenly ends.
-at Reading, the two platforms with third rail electrification that are set aside for SouthWest Trains services to Waterloo are always incorrectly occupied by FGW trains.
-the sun visor is either up or fully extended... on the DLC class 87, you can adjust it as much as you like.
-there's no stop boards on the platforms so you don't know where you're meant to stop, meaning you can have some cars unable to open their doors as they're no on the platform.
-the glow from signals is visible from the other side... you see these coronas off in the distance and are unsure if it's facing you or not.
-there seemingly only four passengers - angular-faced woman in bellbottoms, MaliA in a brown suit, haughty blonde in a woman's suit, and gormless man in a puffy jacket. You will see half a dozen identical people on each station platform.
-the guard closed the doors early and the station staff dispatched me, even though the signal at the end of the platform was still at danger because I wasn't due to go for another minute.
-the digital speedometer in the HST does not work.
-even if your train is due to depart, if you press the 'open doors' button, they spring open and passengers spawn as if they've just gotten off the train.
-there is no buzzer from the guard to advise the train is ready to depart each station.
-there are no London Underground trains at Ealing Broadway or Royal Oak near Paddington.
-none of the HSTs have a TGS car (with guard's compartment) at one end.
-if you are driving along at 125mph, and use the 'rear' camera to view the rear power car, there's an identical ugly cunt driver sitting in the cab. Nobody rides in the rear cab. Neither he nor the one in the front are actually touching the controls.
