I saw Lord Nelson on a low loader passing through Stoke on Trent on the A50 towards Derby on Friday last week.

Can anyone tell me where it was en route from and to please.?

Thanks.......Bob.

We gave the thing an FTR exam yesterday, making sure nothing is about to drop off when it recommences trundling up and down the MHR. We had to hook up a 37 to it to give it some suck to adjust the vac brake system as there didn't seem to be much adjustment left on the first pinhole of the brake puller.

 

The (*****ing) thing was also lit up.

Can you explain that a bit more Phil? Pinhole? Brake Puller?

Basically there is a vacuum brake actuating cylinder set vertically between the frames. The piston rod of this is attached to a bellcrank which converts vertical to horizontal movement - this in turn attaches to a heavy rod running lengthwise along the centre of the loco for the length of the driving wheel wheelbase.

 

At 90 deg to this rod are beams which are attached to the brake blocks themselves, so when the brake lever is operated this moves the main rod (brake puller) which applies the braking force to the wheels.

 

This brake puller is split between the driving wheels, the rod having pin and clevis joints between opposing ends which are threaded left- and right-handed and attached to each other by a turnbuckle. This means that the individual beams acting on each wheel can be individually adjusted to give equal braking force on each driving wheel irrespective of individual brake block wear.

 

Sometimes you run out of adjustment on the turnbuckle, the ends being pulled up so there is no space between them so therefore no more adjustment. On 850 a second pinhole, or a second hole for the pins which hold the various sections together, is provided which means that by moving the pin out to the second hole you can virtually start again with the turnbuckle adjustment.

 

To carry out this adjustment you need to be able to operate the vac brake, hence the 37 being hooked up to provide the suck nas 850 was not in steam.

 

Hope this makes it clear, sorry it's so long winded.
