ive noticed that to,like the class 377 was made by a 3rd party and doors open to,and the class 47,and 37 are ok but have you seen the class 50 on the Trainz 2006 that is a disgrace to the class 50,the graphics are awful on that,and so is the horn which sounds like an american loco!
got to say i dont like trainz railway simulator but the 2004 is surely the best,but i forgot to mention the graphics on every loco is very square too,
