Hi all I've found the relevant data I need for FB track but I've seen some images of Irish 3ft gauge with BH/chaired track. I was wondering if anyone knew anything about it.
This is Ballycastle

I've also seen it on CDR, L&LSR and T&D photos. 
Would this have been handed down stuff from standard/5'3" railways?

The Festiniog also used chaired bullhead track and the chairs and rail were smaller in size than standard gauge parts.

Morning Jim

Are you sure Ffestiniog uses different rail cross-section? I seem to recall that they received a donation of ex BR BH rail.

I'm sure there was a conversation here in which it was said that the wheel treads were the same as the mainline- just that the diameter of the wheel was smaller.

Of course, I may be entirely wrong on that- so please no one take that as gospel.

Derek,

The bullhead rail used on the Festiniog was around 50lb/yard,  the latest bullhead rail for the Festiniog being 48lb/yd and replacement rail from Penrhyn Quarry being 50lb/yd.

http://www.festipedia.org.uk/wiki/Rail_weights

The modern day bullhead rail on BR was/is 95lb/yd and I think main line rail weights in Victorian times could be down to 75-80lb/yd.

So the Festiniog rail would have been noticeably smaller in dimensions to standard gauge rail.

I remember this from many years ago when I contemplated modelling the Festiniog in S scale and I remember researching suitable rail and chair sizes from smaller scales.  I had to rely on Google this morning to remind myself of the details. :D

Jim.
