Hopefully an ex employee or enthusiast can help me with a small quandry?
I can identify Blue Star control cable on loco fronts, along with the vacuum pipe and such as in this picture http://en.wikipedia.org/wiki/File:Multiple_working_equipment_on_40135.jpg along with ETH jumpers on other locos.
What I'm stuck on are the other 2 pairs of pipes with the circular connections, one pair yellow, the other red. Can anyone tell me what these are please?
