The wheel steering mechanism looks really complicated. I don’t understand why they did it that way. Why not just mechanically bisect the angle between the two cars.
The whole thing is immensely complicated and expensive to maintain. But they wanted ultra low floors (hence the name) and this is probably the only way to do it.
Seems like they could have used four wheel trucks and lost a tiny bit of floor space. If the floor space was that big a deal they could have added some smaller idler wheels. It also seems like they could have added a little mechanical linkage between the two cars to bisect the angle between the two cars and used that as a steering input.
I would really like to know the evolution of this solution.
