- Ole, it sounds like (to me) that you are describing a track guage.
These would not be for cutting the plastic, but to verify that you have
not distorted the rail spacing as you shape and secure the track There
are both two point (for measuring spacing only at that point), and three
point guages (for measuring, or holding the correct spacing [betwen the
rails] at a point separated from an other point. I was able to buy some
from Republic Locomotive works at:
16 Little Cape Horn
The part numbers are; RLW 2428 for the standard guage, and RLW 2429 for
the three point guage. The price for each was US$ 2.95 as on the May 23
1998 price list. RLW is a specialty supplier for Nn3 guage trains in
the US. It is a part time business run by Marshall Thompson. His wife
runs the place during the day, and he answers technical questions in the
evenings and on weekends. Their phone number is (360) 577-6479.
I have no connection with them other than as a satisfied customer. By
the way the three point guage is designed for code 40 rail. The Nn3
crowd do a lot of hand laying of track. RLW also sells skeleton
switches of all types (number sizes IE 4, 6, 8, and Ys). the switches
hve no ties (sleepers) but you can buy those from RLW also (both wood
and printed circuit types, the also sell the code 40 rail.
