This is the pipe that often is seen along the LB&SCR E2 Boilers. It was originally part of all the SCC E2's and the variants yet they have on some been causing print rejections in WSF so sadly I have had to remove them from some and add the pipe here as a separate purchase in stronger materials. My appologies for this.
It would be better adding the pipe here than making it even thicker as it would be way to fat otherwise.
Please refer to prototype photographs for exact fitting placements.
As a now separate detailing item it likely would suit other similar locomotives too.
