Engines

An engine is required for each train. Engine can only be swapped before the game starts. The game is over when the engine crashes.

For balancing reasons, engines have different max wagon capacity, water capacity, and initial speed at the start of a biome. The max wagon count increases by 1 for each Biome completed.

	Name	Start Speed	Max wagons	Water capacity	Note	Handbook description
	Hydro Coaler	1st station	5	60.0s	This is the default starter engine	The Hydro Coaler Engine is a time-honored choice for railway construction. It features an essential water tank that requires regular filling to prevent overheating.
	Toy Engine	1st station	4	60.0s	Infinite lifes, When crashing you restart at the last station.	A toy engine for those seeking stress relief. In the event of a crash, the engine always restarts from the last station. No highscores are recorded but savestates can be loaded multiple times.
	Pusher Engine	4th station	6	40.0s	It is fine to crash the first wagon (unless that wagon is essential)	An engine that can be placed anywhere in the train configuration!
	Spectral Express	1st station	5	40.0s	Players can pass through the engine similar to a Ghost Wagon. All wagons start with 4 extension slots with a free Ghost extension in the first slot. Wagons gain an additional extension slot for each 2 Biomes completed. Train length is capped at 5 wagons and does not increase when completing a Biome.	An ethereal engine that allows passing through. It also adds an extra slot with a ghost extension to each attached wagon. It however does not grow beyond the initial wagon slots.
