I wonder why CFD is starting to go towards 2 bay stations now. 14, 28, and 29 are all 2 bay halls but they were built ages ago. Newer halls such as 42 and 45 are 2 bay halls, 38 will be 2 bay and I heard something about new Station 1 being two bay. I don't know if it's going to start becoming the norm or if it's just because CFD Brass doesn't have any plans for stacking these halls with more than CFD apparatus.
It's a 2 point system that the CFD is starting and building their newer stations on.
1) Resources. Halls like 8 or 34 are starting to phase out. Apparently, they are starting to go towards resources split up, instead of having "stacked halls" (3+ units). Especially with Ladder-Rescue swap, they want fewer halls with 4+ bays and fewer halls with only a single bay.
2) Station footprint. They want less "Fire Stations" and more collective buildings. IE apartment building (6/17), community hubs (42/10/43/30) or the Multi Service, (8,26,31,32,34). So having the fewer bays, they give more space up for those other buildings.
On another note, the plans for 17 Station show it's going to be 5 bays, and all folding bay doors. Be interesting to see the practicality of folding doors, as they may save time. But also love how 17 is breaking the mold and putting so many bays in one hall. I would imagine with the new hall comes a rig swap too.
