A grey day at Carmuirs Triangle and the Longannet Branch

The massive Falkirk Wheel linking the Forth and Clyde canal with the Union canal dominates the background as an unknown class 170 turbostar comes by with 2J44 0928 Glasgow Queen Street to Falkirk Grahamston. Carmuirs West signalbox is visible too.

A move now to Larbert Junction at the northern point of the triangle. The up Highland Chieftain, 1E12 0755 Inverness to London Kings Cross has the road to the left with signals Larbert starter LJ5 and Carmuirs East distant CE5 both off.

Larbert Junction's Caledonian Railway built signalbox sees 170457 pass by working 2N65 1018 Glasgow Queen Street to Stirling. Just behind the unit driver would have noticed the distant arm, which is a repeater for the next distant, is at caution.
