Russian term or phrase:хвост крестовины
An excerpt from Russian building regulations (SNiP), and the proximity of pipelines to railways:
Расстояние от газопроводов и тепловых сетей до начала остряков, ***хвоста крестовин*** и мест присоединения к рельсам отсасывающих кабелей должно приниматься не менее 3 м для трамвайных путей и 10 м для железных дорог.
The first paragraph of this section (4.16) was the angle at which pipelines must cross railways and roads.
Multitran gives many possibilities for крестовина, but without seeing a picture, I cannot tell which it is.
