Well, like Harry said it soulds like you need an up grade. My now 5 month old lap top can run Trainz Classic, but it is still slow. Also you can speed it up by cutting down on detail along the route. You can download the Low-Vs, R12, R27/30, R32, R33, R36, R46, and R46 GOH from download station. The R1, R40, and R62 can't be downloaded at this time by anyone. Those who have them are the only people you have them as part of several special releases. If you do get Trainz Classic, it comes with alot of Metro North cars including the M7s and ACMU cars.
