The bullhead rail joiners are excellent, a bit tricky to slide on to the rail- a little filing of any burrs is needed- but they seem to grip well- much better than the N gauge joiners I have been using for C&L . It should be possible to avoid the missing sleeper syndrome at track joins!
I found mine at Frome Model Centre where their supplies of track sold out very quickly.
I'm very pleased with the new bullhead track, it feels very well made and looks superb- points please!
