Changes

The bolts can be used for various upgrades to your [[train]]. You can either upgrade an already existing wagon to perform better. You can buy a new wagon that can fulfil another task or you can upgrade your engine. Upgrading your engine will slow down the train and will allow you to move into a new [[Biomes|biome]].
