Building of the model 
A suitable chassis for  Ma is Minitrix Ae 6/6 
 
 
 
 

                                   Minitrix89/90 catalogue
Chassis during modification
 
The chassis is a bit to long to be in scale. 
A few millimeters at each end of the metal body is cut off.
 
Converted chassis  
New sides for the boggies was produced of styren sheet
Rather simple design but more like the prototype.
The front couplings are taken away and replaced with a snow plow. 

The chassis is still too long to be in scale so even the body has to be enlarged a bit.
It is possible to extend the distance between the windows without losing the character of the body. 

Drawing   
A drawing of both the body in scale and the extended body. 

 

Body:
The body is scratchbuilt with styren sheet in two layers
  The inner layer 0,75 mm 
  The outer layer  0,125mm, with cut out windows  
              
The roof is made of several layers of bonded styren sheets that have been filed to get the right form.
