This nice N gauge loco pack by Tomix is 92123, a JNR / JR Usui Toge Pass twin EF63 set.The leading EF63 is powered while the trailing loco is not. 

 The EF63 class was specifically built in order to work as banker locomotives on passes like the Utsui Toge, they were first introduced in 1963, and a number remain in preservation. 

The train is in good condition as you can see in the pictures, it is tested and runs well and the overall condition is good. It comes complete with its box. The box is in shelf worn condition. 
Overall this is a really nice scale train and would look fantastic on a layout.
Do please have a look at my other listings, I typically have various HO and OO locos on offer as well as an extensive range of imported N gauge locos and other items. 
Note: I do recommend all locos are cleaned & serviced, as they have some age to them even if the quality looks at the highest level (fairly standard advice for all locos!).
