A few different designs of passenger cars were released for Tomy's Super Rail system of trains, with a few types of long four-axle carriages as well as additional intermediate cars for a few of the two-axle trains.
Appearing first in the later 1972 System 3 set with the ED-75 were nice two-bogie blue SUHA 43 coaches. These were also released separately and used in some later sets.
This particular example dates to a 1990 copy of the Shinkansen and Steam Locomotive Wide Panorama Set, pretty much the last time this carriage was produced.
In 1976 intermediate cars for the Tsubame Express Train were released individually.
111 series Tokai type express train cars also began being sold individually in 1976.
In 1979 a 24 series Ohanfu 25 class sleeper car was released, resembling those used on the Blue Train sleeper express trains that rose to popularity in the 1970s. They were first released with a set with a blue version of the ED-75 to represent the EF-65s on Blue Trains at the time as well as individually and in 1986 appeared in a set with the EF-66 Electric Locomotive with Headlights and Whistle after EF-66s began being used on some Blue Train services in 1985.
These cars are pretty nicely molded and detailed, with a FUJI headmark sticker on one end and nicely molded details on both.
The chassis has hanging undercarriage details and the bogies have nice molding as well. It isn't model train quality, and is all plastic of course, but it does look nice for a toy.
Red passenger cars sold individually and in a set with a DD-51 diesel locomotive.
