Is this the sound you heard, from 0.25 onwards, which is the Westinghouse
pump

Another youtube video showing N7 69621 with Westinghouse pump working.

The wonderful sound of Westinghouse pump.
The 'thump thump' rhythm simply isn't complete without the 'bang/clatter' supplanted by some choice swearwords as the Driver knocks seven bells out of it with the coal hammer...... :D

Donkey
 

One day we were running from Liverpool st. to Enfield with an N7 0-6-2 tank when the Westinghouse pump or donkey stopped working. The best way to restart the donkey was to belt it with a large hammer, this usually did the trick but on this day after a couple of pumps it stopped again.
The driver said to me you'll have to stand on the running board and keep hitting it until we get to Enfield. So there was I in the pouring rain standing on the running board belting the donkey, this I did for a couple of miles until we reached Enfield. I wonder what todays Health & Safety would make of that.:D

More on 'ticking over'
 

The only time I have heard railway engines 'ticking over' when stationary, is in films or documentaries.

I didn't hear it at the Severn Valley Railway. I just took the opportunity whilst there to ask a question about it to some of the railway enthusiasts present.

I am sorry to have misled everyone.

But the following from chuffchuff and locojoe is very close to the sound I remember.

Many thanks

I love that sound too. I love all train sounds, especially when you start up a diesel train that hasn't been run for a while and it sends a huge plume of exhaust into the air.... the best!

Can recall a similar tale.The westinghouse pump stopped working, however it can of course be operated 'manually'. So for the 50 miles back to the shed the fireman had to sit on the running plate in driving snow and at speeds of upto 50mph operating this pump (luckily there were a couple of other individuals on the footplate to fire!)!

Westinghouse pumps
 

Hi Jim our Westinghouse pumps on N7s back in the 1950s could not be operated manually, well I never saw one being worked like that.

Maybe ours were a different type to the pumps your talkiing about.:)

locojoe,
The scenario I'm on about was on a European loco, where some locos have Westinghouse pumps which have a type of ratcheted handle so as to move it manually, usually administered with the steam valve open and a good clout of the hammer!

Sorted
 

Well thats sorted then.:D
