Introduction tot the prototype
This photo shows the Di3.643 in Røros with train 301 on June 24 1996.
This photo, from Stig Baumeyer, shows the Di3.642 in ny design but before cab 1 got isolated. This is between 1986 and 1990/91.
Models of the Di3.642 and Di3.643
In the photo two versions of the Di3.642 can be seen. Both are the original Heljan model, one has been weathered (by NMJ). The Di3.641 is a model that I created, see Heljan Di3.641 nydesign (renumber/DCC). It shows the Di3.641 in ny design but before it got the new glass in cab 1.
The idea of this project is to use the windows from one of the Di3.642 for the Di3.643 and make a version of the Di3.642 that is similar to the Di3.641.
These three photos show the steps. From both models the windows are being removed. The new panser (hardend) glass is moved to the Di3.643. The Di3.642 gets the standard windows and the typicall norwegian gitter (steel bars in front of the windows).
