Martijn - can you please do me a favour? Can you please look at the interior lights that fit a tomix 300 series. I know the tomix 785 and 797 (6 pack) fit but they are not available from anyone anywhere (not even in Japan). What else fits? Had anone tried to fit decoders to the tomix lights? any particular points I need to be aware of?
I have fitted Kato 29-353 decoders to all my trains so far except the Tomix 300 series of course. Where the train does allow the Kato 29-353 decoder to sit neatly against the Kato LED lights, I have wire soldered them in.
Works great. No flickering unless the wheels and track are dirty.
According to the catalog, you'll need either 0752 or 0782 for the motor car(s) and 0751 or 0781 for the others.
0781 and 0782 are kits with constant lighting. They're all yellow however, which might not be the best for a shinkansen.
The catalog doesn't mention whether or not 0785 fits, it may be 0785 is just a white LED version of 0781. As for availability, they should all be available from Tomix, so ordering them may take a while, but they should be available.
I've thought about adding decoders to the interior lights, but on a 16-car shinkansen it'd get too expensive =)
