What i was thinking is this. Build a west graal station or hub for the returning railroad system on Belle Island. why you ask??? Simple not only could it serve as a general station for the railroad but turn it into a new tower. Set it up like the castle with multiple rooms and a flag room, with signs directing graalians where to go. Have a room with multiple sets of tracks leading out with signs showing which area those tracks lead to. such as north to mod city or south towards swamp town. Throw in a gift shop with hats, and decor for your house, bomb/arrow and draisalin vendor for noobs that don't have 1 yet. Then turn the other train place just south of nexus into the east graal station with intersecting tracks leading out to different areas n,w,and s and a draisalin vendor. The only other viable place i could see putting in this tower/general station would be replacing the dojo/practice spar and moving it to Balamb Island since its geared towards noobs anyways. And it might be better to have a general station smack dab in the geographical center of the map. I figure if you build a tower with the rail system your killing two noobs with one stone.  

maybe more than one Station and custom Drasines for more than one person where you have to pay 5 gralats to Drive them like a real Station
Similar to the era train system  

you mean like a full train/mono rail for several ppl or just 2 ppl?  

several
