How do they fill RHTT's? I'm assuming it's a 'hosepipe' from the depots washing facilities. Is it a decent sized pipe that fills it quickly or a couple of garden hosepipes?
You could fill an oil tanker with a garden hose (I'm not standing and holding it though).don't be silly they are several thousand litre tankers :roll:
don't the chemicals arrive by road in one thousand litre IBC's?
From a websearch I assume RHTT means Railhead Treatment Train
At Peterborough, we have 2 huge tanks that are filled whist RHTT on circuit then when they come in at night, pumped from tanks into wagons
Ah, smart move on the electric bills too.
A good hosepipe will shift 1000 litres per hour so it's not that silly.
How long have RHTTs been in operation?
Our WCML south circuit leaves Bescot at 10:50 am and returns there at 0632 the next day.That leaves 4 hours to fill up at least 12,000 litres and fuel the locos. We are going to need a bigger hose!
So have these replaced Sandite trains that I remember.
Think he was intimating that while the units are out and about spaffing their load the tanks at the depot will be trickle filled by a normal water supply. Easily enough time and at no cost other than the water itself.

They have been operating in various guises for about 10/12 years now, perhaps longer.
Sort of. AIUI depending on the letter designation in the headcode it shows whether the train is water jetting 3J## or spreading sandite (traction gel) 3S##. Perhaps a more learned person will be able to clarify.So have these replaced Sandite trains that I remember.
Have they stopped coming out of Kings Norton now then or is that just the West Mids circuits?
Once a RHTT train has passed through how long before that section of track needs re-treating?

Do NR still own/operate the ancient former Southern Region EMU vehicles (were they EPB's?!) converted to sandite trains and painted in Railtrack's brown livery? Or are they long gone?

Didn't a couple of the EPBs make it into blue and green railtrack? It looked smart if you ask me, but I was just a nipper at the time.

to provide enough water capacity for such a long diagram.
The Cambrian/North Wales and Cumbrian trains are also triple sets.
So those trains can use three hosepipes and they will be filled in no time!!
