Tomytec is in a rush

[Kabutoni]

So today Tomix updated their Tetsudou Collection. However, they were in such a rush apparently they put an incomplete model on the website. The Sangi RR units will now never be able to run in 2+2 formation ;_; (albeit dummy couplings)

I'd say the end without couplers will have a rapido coupler to couple two sets together with the scale dummy coupler on the outer ends.
