To guarantee that one will be produced by Kato, I starterd work on an N scale Amtrak Ex-Metroliner Cabcar...

This is made from a Kato Amfleet I coach where I added a cab front from Fusion Scale and mounted more correct trucks.
While one could probably get away with simply mounting the cab section right on the end of the stock Kato coach, I wanted the overall length to match the other Amleet I cars.
This required a bit of careful surgery to cut down the overall length and relocate the door on each side behind the cab (this styrene was rather pungent to cut into and file!).
The trucks were anything but simple to replace, as the stock Amfleet I cars have a rather unique mounting system vs. the more typical screw mount.
The pilot with plow was made with spliced up parts from the Kato Surfliner cabcar's front coupler assembly that were mounted to some styrene.
A small window opening was also added behind the last regular window on each side as per the porototype (before there last major overhaul).
