Exploration Train with deployable vehicle
A train that acts as a mobile base of operations/exploration that comes with a small deployable vehicle.
With a top speed of 200 km/h, this train can fly down the tracks, and barely uses any of the onboard fuel to do so.
It has everything you would most likely need while exploring, including a medical bed and various outfits. There is a single thermostat in the mess hall that controls the heaters across the entire train. The interior areas (basically not the vehicle bay or cab) are fully sealable, giving you a safe place to bunker down during a tsunami.
This train has successfully travelled from camodo station to magnus shipbreaking Ltd (a total of over 70 km of track) without stopping, overheating, or derailing at an average speed of 240 km/h.
