The 4MT sees its first fire!

I took the new 4MT Standard Class Tank loco to Urmston club on Sunday for its hydraulic and steam test, and to see how it runs.

It passed both tests with no issues at all. A few teething troubles were revealed on running it, but once those are put right under warranty I think it has the potential to be a superb locomotive.

The pictures tell the story.

 On the prep bay. I'm replacing the two safety valves with one blanking plug and one blanking plug with a connection to 'Boiler' Bob's (standing next to me) calibrated pump and pressure gauge (behind the loco).

I have filled the boiler to the brim with water, and Bob will pressurise it to 1.5 times working pressure (135 psi for a working pressure of 90 psi). If it should fail (which it won't as it has a manufacturer's shell test certificate to twice working pressure) there will be no explosion, water being incompressible.

 With its door open so Bob can check the front of the boiler for hydraulic leaks, here's a look into the smoke box. 

The blast pipe is in the foreground (the exhaust steam from the cylinders exits her to blast up the chimney), below the skirt of the chimney petticoat. The two big copper pipes exiting the sides of the smoke box are the superheated steam feeds to each of the two cylinders from the superheater header.

In the background is the the front tube plate of the boiler showing the boiler flue tubes that run through the water space from the firebox at the back of the boiler.

The partial vacuum formed in the smoke box by the blast pipe is what draws the hot flue gasses through the boiler tubes and draws the fire to almost white heat when the loco is working hard.

The small copper pipe into the side of the blast pipe feeds boiler steam to the blower, controlled from the cab this gives a blast up the chimney to draw the fire when the loco is not on the move.

The steam test followed the hydraulic test. This ensures that the boiler has at least two methods of getting water into it (the 4MT has a live steam injector, a hand pump, and an axle pump) and that with full blower to give a maximum fire the safety valves blow off at or just before working pressure is reached, and can dissipate the steam at a rate that holds the boiler pressure within the limit. 

After I'd driven the loco around the track a few times 'Boiler' Bob has a go, watched by Malc. Loco blowing off healthily through both safety valves!

The 4MT in its element - albeit on the short Urmston track.

Note that the cylinder drain cocks have not fully closed hence the steam from the front end, one of several 'teething' faults to be addressed before we take her out on the main track.

It's arrived!

The Kingscale 5" gauge BR Standard Class 4 tank loco arrived this morning in a big wooden crate, all 15 stone of it. Once the rain stopped and I could wheel the motorbikes out of the garage (I needed to use the motorcycle lift) I could begin unpacking it.

The delivery man used his tail lift and pallet truck to unload it, and we got it onto one of my hydraulic trolleys so I could wheel it into the garage out of the rain. I used my electric drill to remove the many screws holding the lid down, observed the crate to be full of plastic foam 'squares' for packing and the loco invisible under a thick polystyrene sheet covered in shrink-wrap plastic. It was packed just as my Jubilee had been.

Bikes outside, end removed from packing case, ready to mate the hydraulic trolley to the (red) bike lift.

After lunch with the rain stopped I filled three bin bags with the plastic foam squares from inside the packing case, then as I had with the Jubilee, used a big claw hammer to lever off the packing case's external battens at one end, bashed the end off the packing case. I got the bikes outside, raised the bike lift platform and the hydraulic trolley to equal heights, removed the shrink wrap etc from the loco, and carefully maneuvered it out of the packing case onto the bike lift.

Shrink wrap cut, polystyrene sheet removed, and loco carefully maneuvered out of packing case onto the lift.

The edge of the packing case was overlapped with the bike lift to obviate the packing case and hydraulic trolley tipping as the 15 stone weight of the loco was moved out of the packing case onto the lift. The removable section of the lift (removable to allow a motorcycle's rear wheel to be dropped) made a good bridge between the case and the lift.

The packing case was then completely demolished flat so I could fit the bits into the car to take it to the tip later, and the 4MT was wheeled off the bike lift onto the hydraulic trolley for a good checking over and some photos!

 Job done! The 4MT on the hydraulic trolley where it will live when not in use.

 We even got a smidgen of sunshine to illuminate this lovely loco!

 Cab roof and back are removable (visible on the right, next to the loco) for driving and firing. The coal bunker is in the foreground (no coal in it yet) beneath which is the bunker water tank to supplement the water supply in the side tanks.

These are handsome locos!

G-BOAC gets a nose job!

Very glad to see that Manchester has at last put in place an enhancement to Concorde G-BOAC. They have allowed Heritage Concorde to re-activate the famous drooping nose, a modification that has already been applied to some other museum-based Concordes.

The mod involves installing a mains electricity-powered hydraulic pump to pressurise the nose and visor hydraulic circuits. The nose now operates exactly as it did in airline service, using the original 4-position cockpit selector switch.

Selections are:

1) Visor up, nose up. The position used in flight and while parked on the ground.

2) Visor down, nose in the 'up' position. The visor has to be selected 'down' before the nose can be lowered.

3) Nose lowered to 5 degrees, the position used for taxying and take off.

4) Nose lowered to 12.5 degrees, the position used for landing to give a clear view of the approaching runway despite the aeroplane's considerable nose-high pitch attitude on landing.

Now that the nose can be lowered to 12.5 degrees, the broken windscreen on the P2 side can be replaced. The windscreen failed about ten years ago and was a constant source of embarrassment to us tour guides as we had to explain time after time to flight deck visitors why the two windscreens were not identical.

Thank you Heritage Concorde.

Here is the nose-droop in action:

The 4MTs are coming!

First batch of 10 (of 50 - all now sold) Kingscale 5" gauge BR Standard Class 4 Tank engines at Northampton for pre-delivery boiler hydraulic test and run-on-compressed-air test.

Should have mine soon!

Nether Alderley Mill produce its first flour for sale for decades.

Nether Alderley Mill

I've been a guide at Nether Alderley water mill since it re-opened in 2013 after full restoration by the National Trust, and a Miller since a year later. We have been milling flour for demonstration purposes during visitor tours since re-opening, but we did not have clearance to sell it.

Yesterday, however, we produced our first bagged flour which will soon be for sale at Nether Alderley, Styal Mill, Harehill, Little Moreton Hall, and used in foodstuffs sold in the Styal Mill restaurant. The hoops we have had to jump through to obtain permission to sell the four for human consumption have been considerable.

We have had to show successful vermin control (almost impossible in a medieval stone water mill) and be compliant in countless areas, have documented processes and signing procedures including batch and individual bag tracability. We had to pass audits by the Food Standards Agency and Cheshire East Food Standards among others, and most onerously internal National Trust standards for food hygiene! One presumes things were simpler back in the 1600s!

Me keeping an eye on the grain level in the hopper as the runner stone spins above the bed stone to mill it into flour

However,we have at last made it. Yesterday a group of Millers took two sacks of Suffolk wheat grain that had been transported from Styal Mill in a catering-approved vehicle and fed them through the mill stones. The flour was sieved to ensure nothing was there that shouldn't be (it wasn't), weighed into bags under sanitized conditions, sealed, and labelled.

From a bag of wheat to many bags of flour

So soon our visitors, and those to other NT properties in our local group, will be able to buy flour milled in our ancient water mill.

Two Jubilees at Urmston

Rain first thing, then dry! Good day at Urmston today.

My friend Adrian from Leeds has a Kingscale Jubilee like the one I had but returned to Kingscale in a buy-back deal for their upcoming BR Standard 4MT tank loco. Fellow Urmston member Trevor also has a Kingscale Jubilee. Both Jubilees were running at Urmston today, and very well they went, too.

I had an enjoyable drive of Adrian's Jubilee 'Trafalgar' and Jim's Venezuelan tank.

Dave prepares his Garratt in the foreground, Adrian's and Trevor's Jubilees, then the Hunslet and the little Manning Wardle. On the left is a 3.5" A3 Pacific - together with Aiden's B1 (which was already running on the track when I took these pictures),and Jim's Venezuelan Tank (which arrived later) that was total loco turn-out today.
The Hunslet didn't run due to a leaking wet header. 

Early rain soon cleared to dry day

CVR's 'Gronk'

John Stein's superb picture of the Churnet Valley Railway's 'Gronk' at Leekbrook.

The loco looks excellent after its re-paint at Cheddleton from faded EWS livery, but it could do with a bit of mechanical TLC.

When I was Consall signalman some months ago the loco was rostered on a service train. The practice, for 'down' trains coming to Consall from Froghall, is to hold the Consall home signal 'on' until the train activates the outer track circuit. The signalman then knows that the driver has that 'on' signal in sight, and that it can then be cleared to 'off'' and the driver will see this. This is 'approach control' and informs the driver, in the absence of 'distant' signals, that although this signal has been pulled 'off'', the next one (the Consall station starter) WILL be 'on'.

That day, the 08-hauled 'up' train arrived at Consall. As I performed the token exchange the driver said "don't bother with approach control when we return from Froghall" (as the 'down' train but UP the valley, so uphill). "If I have to stop at the signal we'll never get going again. I'm supposed to have 360 horses under the bonnet but 275 of them have escaped".
