Modern station or great triple lunar base (100 m in diameter and 50 m high, but 248 m long with 3 domes). You may join many stations with tubes. It is better in surveyor to put buildings before, but roads, tracks and catenaries or maglev can be placed after it. I will multiply objects for this kind of stations and you can do it.
