Mod TRAIN TRUCK FOR SNOWRUNNER

The update added a train horn. train wheels or rail mud tires should work on train tracks can be a cool idea for modified maps
The update added lights on the train truck and trailer. train horn will be added soon
This is not the final version just fiddling with the new Pts phase 3 train trailer
i plan to add lights and train horn later
There's a steered train in the cargo store
and a train trailer in a trailer store
