Train > Sliding Bricks based on x946

[Magnus Forsberg]

I am done with the sliding bricks.

-> Should we call them in a similar fashion? 

• x946a and x946b
  

-> Shortcuts

• Coloured wheels, please
  

x946ac01 and x946bc01

-> Origin
Any unofficial part called xYYY.dat will loose the x on release, and becomes YYY.dat
Changing the origin is Ok.
