 Tomytec Power Chassis Dimensions


Tomytec and Other N-Gauge Power Chassis Dimensions

by R. D. Kerr
(Revised March 1, 2017)

This is a listing of Tomytec and other power chassis. They are useful for powering not only the rolling stock for which they were intended, but other trolleys, trams, railcars and various "critters" that are scratchbuilt or sold as shells. Their various basic features and dimensions are provided to aid modelers in determining the most suitable power chassis for their needs. For the Tomytec power chassis, I have gone through the laborious process of converting actual millimeter dimensions to scale feet and inches in 1:160, 1:150 and 1:148 scales. Chassis that I have measured myself using digital calipers, or others have measured for me, include TM-01, TM-02, TM-03, TM-04, KD-25, TM-05, TM-07, TM-10, TM-11, TM-19, TM-21, TM-22, TM-LRT01, TM-LRT02, TM-LRT03, TM-TR01, TM-TR02 and TM-TR04. If you have additions or corrections, please post them to groups.yahoo.com/group/tomix. Thanks!


TOMYTEC

Tomytec power chassis are made to add power to various Tomytec Tetsudou "Railway Collection" series static display cars. Chassis are produced in limited runs, as needed for new car production runs. They are not kept in continuous production or stock. Tomytec uses nominal metric prototype chassis length classes and a letter code for model truck/bogie axle center spacing: A = 14 mm, B = 16 mm, C = 12 mm and D = 15.4 mm. At times designs are revised and receive an "R" suffix.

EARLY REGULAR CHASSIS

BACHMANN
The similar Bachmann Brill and PCC trolley chassis are oversize, toy-like and of inferior design. I list them because they are common and inexpensive. Their early white axle gears usually split; use only the later improved chassis with black axle gears. Their wheel diameter is 5.6 mm, and Bachmann started blackening the wheels by 2010.
The more recent Bachmann Peter Witt chassis is much different - a smaller, more sophisticated design. Factory-equipped with DCC, it can operate under DCC control or analog DC.)
