how many mine engines are in A bumpy ride and what basises do they have

I found that A Bumpy Ride uses Unreal Engine 5.

For the “basises ” part, the available listing describes it as a cozy train-driving and exploration game inspired by 19th-century railroading , with a whimsical open-frontier setting.

What that means

• Engine: Unreal Engine 5.

• Basis / inspiration: 19th-century railroading and frontier train travel.

• Game style: cozy, casual, exploration-focused train driving.

Tiny clarification

If by “mine engines” you meant something else, the exact wording is a bit unclear. Based on the game listings I found, there’s one engine listed , and it’s Unreal Engine 5.
