>>7541406Heh thanks, until relatively recently I never gave greebling much thought, though I was unconsciously doing stuff along those lines already. Would love to see an epic monorail setup like you're describing, good luck with that heh.
>>7541457Normal flight crew is probably 3-4, though it can fit everyone if necessary. Yeah it all started with that one submarine, then another, then a submersible starship, and so on...
Pic is that second addition, originally intended as a base of operations for exploration while its tug and the other sub would seek out resource deposits. It largely retains that role in the greater scheme, acting as the nerve center for all the modules. It also acts as another "caboose" section for transportation.
