Rail Handcar
From The Blockheads Wiki
Rail handcars are a mode of transportation. They are used to travel long distances across rails. It cannot carry more than 1 blockhead in this trip.
Speed
The speed of a rail handcar is generally faster than a steam locomotive only when it is traveling downhill or flat ground but is slower when traveling uphill, resulting in the player slowing down then falling back downhill. As rail handcars do leave their rails, it is possible to do hang time in the air once a rail handcar goes on a ramp and take off. However, speeding can cause a blockhead to lose health for e.g. A speeding hand railcar will despawn when it reaches a gap, damaging the blockhead.
Fuel
No fuel is needed to operate a blockhead.
