Hi, thank you for your suggestions! There are a few relevant parts already on the Roadmap, such as a map and a 'permanent log'.
Messages for when you see Santorini destroyed from a distance are also planned. The tram has been reworked a bit in v0.4, but being able to reverse the direction of it mid-way to avoid dying is an interesting idea. It's not possible with the game's current feature set, but I'll add a note to look into it in v0.5
What if it was an automatic action, rather than a manual one? Say the Tram detects a lack of railway (due to an explosion), and so it returns to base automatically.
Though even if you could travel back to the base, there would still be an issue. You'd get in your rover, drive back, but you'd have to pass through Santorini, in order to get back to Talos or such... unless you can drive by destroyed Santorini... I've not tried, so I don't know.
EDIT:
However, then there is a further problem. Even if you could drive by Santorini, there is no current action to drive back towards the Dam, so you'd be stuck at Santorini's crater.
