Well done so far Paul,fantastic demo showing the potential for something that could be quite special.
Not had any issues,running similar to Chris (CJBarnes) but with a GTX1070 installed. FPS very smooth etc.
I do have a couple of queries; firstly,the levers and bells pull themselves (though I can still play with them),I'm guessing from what I have seen that we are intended to watch and enjoy the spectacle from the box (which is very enjoyable!) rather than mess about? I note that when I did put a signal to danger,the train ran through the red signal.
Otherwise it's fantastic,great sounds and visuals,the HAA's also seem to shake as they go past,but again I'm sure you're aware of that issue.
All in all fantastic demo,superb atmosphere and definitely something that will be worth purchasing when it's completed if current progress is anything to go by!
Cheers,
Mark
