What's also interesting is that it seems like the station was designed with space between the rails in the first place. I find this unusual. Usually, light rail or subway is designed with either an island platform or two side platforms.* If there are two side platforms, they are designed with the train tracks right next to each other with no room for an extra platform. So why was there space left here between the trains in the first place? Were they expecting to accommodate transfers here originally?
Before that, the buses ran on trolley wire, and each platform had a passing wire. I remember riding in the bus behind another coach, and the driver was saying under her breath, "Don't take the passing wire." That being said, I rarely if ever saw one bus pass another bus at a station, even if the forward bus was loading or unloading a wheelchair or if coaches were stopped at the rear of the two stops. Especially once trains started running and the buses were off the wire, they were absolutely paranoid about a bus and train collision that they didn't let buses use the center lane. However, one time I saw a bus break down at a station. They finally moved it to the center lane so buses and trains could pass it.
