Front, rear axle with the pneumatic connection points. Image too big Image too big Image too big

I'm afraid, you're right. It was a good idea, but I have not tried it yet. I will try to create a solution, but don't know, it is possible with lego parts. Thanks your help. Master valve isn't important in this bus, but later, I will make an articulated version. In the real life, the articulated bus has this master valve for 4 doors.

The master valve will work only when switch 1-2-3 are in closed position. And it is true reverse too. Switch 1-2-3 are working with closed master valve.

Interesting idea, but it's a little bit difficult. Pneumatic not so precise to stay in a specific level, I think.The pressure switch has the same problem. It has big difference between the work/not working mode. Pneumatic cylinders have big latency in this construction. And you need install an unload valve too :) Maybe in the next bus, but not now. Earlier link is helpful, thanks. The shape will little bit similar, but better outfit.

My idea of the pneumatic operation:

Could anyboby help me, how upload more pictures? I make pictures of course.

I have an old idea, to make a full pneumatic bus. All function is operated with pneumatic. Functions: Pneumatic suspension Pneumatic kneeling function Pneumatic opened doors Motorized compressor with pressure switch to suspension air circuit Motorized compressor with pressure switch to the doors HOG steering I will choose an old styled yellow model with new doors.
