Question about track maintenance train

[math1985]

Last week, I heard this maintenance train passing by from my apartment:

http://www.realtimetrains.co.uk/train/H33794/2014/06/05/advanced
(TRUST ID 42300HC805, Running as 300H, VAR schedule UID H33794, Service code 53790132)

The train made a very loud sound, much louder than the regular diesel trains passing by. Just wondering, does anyone know what this train does and why it is so loud?

 

[strowger]

It's probably either a stoneblower or a tamping machine. Both are yellow and irritatingly slow and loud if working nearby at night.

don't think it would be a Tamper/Stoneblower on a 3XXX Headcode? Possible some sort of Test train?

Not many track machines are timed for 75mph are they?

class 60 hauled ?

It will be a test train rather than a track machine if it finished at the RTC. It will be formed of a couple of carriages and a big diesel locomotive on the front. It will be loud as it is hauled by a piece of 1950's/60's technology when environmental concerns were not paramount in deign

class 60 hauled ?

Wouldn't that make it 60mph?

Wouldn't that make it 60mph?

Not if it's been re-geared

Thanks for the answers! It was indeed yellow, but I don't remember exactly which of the trains on that page it was.

I like the sound of that!

He just passed again:

It makes a strange pulsating sound.

Train 3Q17 which would be a test train of some description - afraid the consist wasn't entered so I can't tell you what the formation was!

It wouldn't be a weed killer would it? It appears to be trying to cover both lines on a route. If they sound anything like the leaf sprayers ...http://m.youtube.com/watch?v=PMhlpgP8XHo

That one seems quite quiet, it's an entirely different sound.
