| Remarks | Illuminated - Truck mounted couplers - With and without window outlines - Note variation in lettering placement on two examples shown.. These cars solved the truck shorting problems caused by metal couplers on trucks conducting power to the lighting by use of an insulated separator on the truck's coupler shaft. | ||

 This
view of the car undersides of a 133 and 135 shows the insulating fiber
spacer used to electrically isolate the coupler from the power conducting
truck. This prevented the coupled trucks from causing a short
circuit. No matter how the identically manufactured cars were coupled,
the conducting wheels of coupled trucks would be on the opposite rails.
This fiber was probably the best they could do in 1947, but it is a weakness
on these cars and is the reason why the coupler arm is often broken off and
missing as is shown on the lower car. Also, the coupler itself is
often broken off at the point marked "Other Problem Area." The earlier
pre war cars from 1940 and 1941 that had truck mounted couplers in order to
negotiate 16" radius curves of the then new Gilbert track had one piece non
isolated coupler arms. They were sturdier, but couldn't solve the
lighting problem and so these cars were unlighted. |
