Bitcoin mining inside electric trains locomotive.

Hi guys i'm a train engineer. Our company has about 350 electric locomotives. The trains have individually extra room not utillized. The room is 3m long, 3.5m height and with is 2m.

Any 'big brains' here could me help out with the math, how many miners could be hosted per engine, how to tackle monitering off the mining from a distance, how many hashes it could produce and the revenue it could yield.

The engine room is pressurized , to keep electronics dust and a stable temperature.

Cooling could be re-routed to keep pace with the rising temperature off the mining.

Hoping for a healthy discusion and great ideas.
