Tomix EF81 DCC Pt 2: Small Victories

It lives! Tomix EF81 with working DCC provided by a TCS CN-GP.

[Update 7 July 2010: The decoder failed by February. TCS advised that the CN-GP is a very delicate decoder; consequently, I cannot recommend this installation method. Currently looking for a new method of installation. Watch for future posts.]

It has a set of markerlights and a signboard that light up when the car is at the rear of the train—which is 50% of the time. The other 50% of the time, when the car is at the front of the train, these lights are all off. One light, one function, easy-peasy.

Review: Tomix 92950 "Yumekukan" (夢空間)

Happy birthday to me! This set was a gift from my wonderful wife. Actually, we kinda picked it out together, for reasons I won’t yet reveal.

The box reads “J.R. Limited Express Sleeping Cars Series 24 Type 25 ‘Yumekukan’ with Electric Locomotive Type EF81″ (which is far more terse in the original Japanese: “JR EF81・24系25形特急寝台客車(夢空間)セット”).
