The Belgian one is inspired by the IC3, there’s a few subtle angular nuances in exterior, but they do look rather similar. Wouldn’t be as hard (I think) if one uses one as a starting point for the other, rather than having to go from scratch.
Also, Ola, I replied to your e-mail, not sure if you got the reply, haven’t heard back yet… :s
You seem to be remarkably busy with helping other modellers and modders finish up their projects too though!
Yes IC3 is a diesel train (DMU) with 3 coaches. And the IR4 is Electrical and has 4 coaches, and is made as a updated version of the IC3.
I agree the nose of the Belgian looks alike, and i look forward to try it! But they don’t have the same shape/design, and arrangement of doors/windows. So i’m afraid it wouldn’t look right to reuse the Belgian AM96.
