National Coal Mining Museum for England Caphouse Colliery New Road Overton Wakefield WF4 4RH. A excellent free entry museum, which contains, amongst a lot of other items, a collection of narrow gauge mining locomotives. Not all items are on public display , but a short passenger line is worked, using manrider coaches[ £1 fare in 2012]. It is also possible to take a underground tour. Definetly well worth a visit and also within a few miles of Kirklees light railway. http://www.ncm.org.uk/
