AH1 had Railway Stations and Depots integrated into its strat for a period of time.
Depots supplied strat to fields via roads. They were capturable. It was basically a Town with a control tower. Capture a depot and the enemy fields it previously supplied were starved of strat.
Stations were integrated more into the City & facilities side of strat. They were not capturable but by attrition you could effect the speed with which cities provided resources to facilities (radar, fuel, ammo etc).
They were removed over time. I quite liked the Depot concept, but it was one that had to be installed into a map carefully. Very often there were too many fields served by a single depot, such that once it was captured the surrounding fields fell too quickly. In some ways I would prefer if every town we now had was replaced with a depot and every field given its own map room.
Stations were sort of very remote...... you knew you were doing some harm to the enemy hitting them but the consequences were less than clear. Without this "game feedback" they became ignored.
