fluid containers? pressure vessels?

[stockport1]

On my way home from liverpool lime street via runcorn
i pass pressure vessels of some soret. they are usually in pairs and sometimes with an accompanying hut.

They do not look operational whatever they are and i guess look older than 30 years.

Any one know what these are?

There is a pair of them at edge hill where the runcorn lines diverge.
There is another pair at weaver junction near the abandonded signal box.

Thx in advance. and sorry i dont jknow what they are called or their purpose hence my asking

LPG for point heaters is the usual guess - especially if they are near junctions...

LPG? I thought Point Heaters worked on Electricity!

Depends on the type. LPG heaters are certainly fairly common.

Not everywhere on the rail network is near a convenient source of electrical power with sufficient capacity to support an electrical heater.

You also sometimes see tanks on the compressed air system for working points. There is a disused example in the up cess just north of Denbigh Hall South Junction LEC1.
