This is a set of TOMIX EF81 electric locomotive (2141) and Cassiopeia basic set (92717). I purchased these used, but haven't had much chance to run them, so I'm selling them. The locomotive is an older item, so its operation is a bit sluggish, but it runs without problems (it might improve with maintenance). I confirmed that only the top light turns on (the tail lights are not supposed to light up?). Both couplers are TN couplers, but Arnold couplers are also included, along with unused accessories. The passenger cars are also older, so the paper sleeves and outer boxes have some damage. Regarding the contents, I confirmed that the lights on both lead cars turn on. Each car rolls without issue. Only the part that connects to the locomotive has a TN coupler, but the original Arnold couplers are also included. - Model: TOMIX 2141 J.R. Electric Locomotive EF81 - Series: JR Ltd. Exp.
