Lithgow Coal Stage Signal Box - Eskbank - built 1925 - see below
The Lithgow Coal Stage Signal Box is of state significance as a large and imposing elevated timber signal box that has remained in continuous operation since 1925. The signal box retains most of its original equipment and is an excellent example of a traditional early 1900's elevated timber railway signal box, sympathetically adapted to operate electric light signals and power activated points mechanisms. It is now one of the largest signal boxes remaining from a relatively small sub-group of standard railway building types. Located close to Eskbank Railway Station, the signal box has strong associations with the surrounding industrial history of Lithgow, and remains as an important element in the evolution of railway operations in the area.
Lithgow Coal Stage Box is the third built in this locality and was constructed in 1925 to cater for the expanded marshalling yards and locomotive depot which replaced the original Eskbank loco Depot. It was a standard design of the period. The box takes its name from the 1888 unique on-line overhead coaling bunker, now demolished, but which existed when the box was built and was situated immediately westwards. It controlled access to and from the locomotive depot, local colliery branch lines as well as locomotives using the 1888 on-line overhead coaling bunker. Initially, it contained 64 mechanical levers but now many of those are not in use. In 1957 with electrification of the Lithgow Yard its signalling system was adapted for changing technology including electric light signalling. The original timber steps have been replaced by metal steps.
