The Ffestiniog & Welsh Highland Railway will be holding its second "Quirks & Curiosities" event 28th March - 1st May 2017, see
http://www.festrail.co.uk/content/publish/news/515.shtml Amongst the many Quirks & Curiosities visiting over the long weekend will be two mine locomotives:
'HISSING SID' - a replica of a 19th century Lishman & Young 2ft gauge compressed air locomotive built for use at the Earl of Durham’s Lambton Collieries in the north east of England.
'EIMCO 401' - EIMCO Works No. 401-216 built in 1968 at EIMCO's Salt Lake City works in Utah, USA. Powered by a 20hp EIMCO ‘Type 200’ 5-cylinder rotary air motor, it apparently started its working life in Colorado and finished with a mining contractor in British Columbia who used it until 2012.
It is hoped that these two locos will be operational in the Ff&WHR's Minfordd yard during the event.
