With the release of the Athearn and Walthers (via the P1k line) GP15-1's there's got to be a detail part for the rear radiator intake (the part that makes 'em look like baby tunnel motors?) Does anyone know if one is available? I checked Cannon and Co... no joy. I remember a model RR magazine article about doing a kitbash before either models came out... but my copy is half way across the country in storage...

I'm putting speakers in mine, and the open grill would help things sound better... I think...


The Athearn Genesis model comes with see-thru radiator grills. The Walthers one does not although Smokey Valley makes a see-thru replacement for it.

oops... oh well...

I was hoping for a cut and replace part, the Smoky vally appears to be the whole shell...

You can always get the part for the new Genesis model and cut out the opening for the grille on the walthers model.
