Train Model Modifications

Ajdin has modeled our train for us but I've made a few small changes. Seems some parts were not mirrored onto the opposite side of the train so I have sorted this. Also small things such as exaggerating the main funnel slightly and changing the driver compartment slightly so that the bullet ricochet section can work as easily as possible. Also made the coal cart smaller as this seemed overly large and unbalanced the main part of the train.
