Lionel 6-6908 PRR N5C "porthole" caboose.
This very basic Lionel lighted caboose was produced as part of the Famous American Railroads (FARR) series in 1984. The series included:
6-9476 PENN single door box car
6-6307 PENN single dome tank car
6-6123 PENN covered hopper
6-9456 PENN double door box car
6-6908 PENN illuminated porthole caboose
The caboose includes diecast non-sprung trucks and a simple sheet metal underframe. The trucks are an unusual "leaf" spring design. The caboose is missing the usual rivet detail found on other similar Lionel caboose models.
