Product Description

This shell is an accurate representation of the NRE 3GS21B in N Scale, with an angled fuel tank and a high mounted headlight to match NS 300. To complete it you will need the parts outlined in this spreadsheet: Google Docs BOM. You will also need an BLMA vapor style AC unit.


You will need to make minor modifications to the frame of an atlas B23-7 with blomberg trucks to make this fit. You will need to remove the bridge that goes over the motor.


Etchings for handrails and grilles are available at
