Pannier Tank

Thank you for asking the question. I wondered if there might had been a 'clearance' issue (future proofing for future electrification) hence the divergence and the use of two arches. With regards to 100 mph running, I guess that East Bound Passenger Trains (I can't get used to the change of Up & Down Direction, it used to be down to Oxford and Up to Bletchley) would be slowing down for the approach to Bletchley Flyover at this point anyway.

As you travel (presumably) wrong line towards the Newton Longville to Whaddon Road Bridge at the Eastern end of the former Swanbourne Sidings, I note the two lines diverge to go under different arches of the bridge. The Westbound Track appears to be laid on it's original formation but the Eastbound Track is re-aligned on to what was the entrance/exit to Swanbourne Sidings. Do you know the reason for this?

It was indeed a rarity to see 46231 at Bletchley, the one and only time I ever saw her. 46227, 46231 & 46232 were all withdrawn in December 1962 from 66A.

I have fond memories of 46231 Duchess of Atholl during the summer of '62 when she made an unscheduled stop for water at Bletchley whilst working an up express. Presumably unable to take a re-fill at Castlethorpe troughs. As she was taking on water the crew took the opportunity to use the coal pusher to bring the coal forward and used the slack pipe to clear the coal dust. My Father and I received an impromptu warm shower! Happy Days.

I don't know about RTT but you may find this useful?

The report says "Horner's position is backed by title rivals Ferrari, world champions Mercedes and McLaren."

The following image shows track laying at a double arched bridge. https://twitter.com/Marshrail/status/1524494908060585984/photo/2 It looks very much like its the bridge carrying the Whaddon Road to/from Newton Longville which was the former eastern entrance to Swanbourne Sidings. The Track looks to diverge at this point with East Bound (former Up) Line using the former Archway access to Swanbourne Sidings and the Oxford bound line using the former through line Archway.

It was the Cattle Market in my day!!

Where Swanbourne Sidings used to be.

Hello Michael, Arduino The Signal Interlocking System consists of an Arduino MEGA which is ok for up to 25 Levers (Inputs) and 25 Locks (Outputs) beyond that you would be looking at expansion modules. I use a MCP2515 CANBUS Module which communicates with the MERG CBUS System to control Signals and Points. I no expert on programming Arduino's, I've learnt by modifying the code of RMweb Member ffayolle (Fabrice). https://www.rmweb.co.uk/community/index.php?/topic/82978-arduino-applications-and-programs/page/4/&tab=comments#comment-2276967 The Arduino Sketch I am using doesn't support reading data from say an SD Card although it should be possible to add this facility. Lever Frame The drawing I posted was really just to show the principle of my idea. I just wanted to produce something quickly so I made use of 'cut and paste'. I need to re-visit it and produce an update. Just concentrating on Moretonhampstead with 12 Levers I hadn't considered if you substantially increased the number of Lever & Locks, the length of the Brass Slide Bars would be unreasonable. It is my intention to mount half of the servos either side of the Lever Frame and as you say the lengths of the tappets can also be reduced to suit each Lever.

I originally intended using Solenoids to drive a pin in/out of the underside of the Brass Slide Bars but I think using two slide bars driven by the Scalefour Lever Frame and Servos with an omega loop would be cheaper and easier to build. The beauty of this arrangement is that the Interlocking can be changed (Software) without too much fuss. If it was purely mechanical then any alterations to the interlocking would require stripping down the locking frame.

It's probably worth posting on the EMGS Forum to a: encourage activity and b: hopefully get you an answer to your question.

Interesting project. I've done something very similar for my Moretonhampstead Project. https://www.rmweb.co.uk/topic/150296-moretonhampstead-signalling/ On your website under Phase 3 - Interlocked switches you mention using solenoids for the locking. When I start on the Locking Frame it is my intention to use Servos to drive the 'Locks'.

Remove the Auto Gear and re-number as 5812. In operation, run round the 'Auto Trailer' at each end of the line.

Thank you for the photograph Steve. I particularly like the middle Lever Frame, a nice sturdy job. It's given me an idea for a Electro Mechanical Interlocked Lever Frame.

Superb Signal Box. I wonder, could we see a photo of the nearby Lever Frame?

A nice backdrop for the Graffiti artist.

I noticed today that the Police Station appears to be vacated; no vehicles to be seen in the front or rear car parks.

The Class 115 DMU's went to Bletchley for Maintenance arriving / departing early evening. This continued until the introduction of the Class 165/0 DMU's and the opening of a new Depot at Aylesbury.

When the Oxford Branch closed to Passenger Traffic the Oxford Bus Company ran an Oxford to Bletchley Service. I remember them being Red Single Deck Buses as opposed to the local United Counties Green buses. This service took the route of the closed Stations and I don't think it lasted that long.

There was a Permanent 30 MPH Speed Restriction in this area in BR Days maybe even before 1948.

I think I may have a 'disassembled' Lima Class 121, in I believe NSE Livery stashed away somewhere, if it's of any use to either of you?

Just had notification from NetworkRail that Track Renewal Work on the Bletchley Flyover between Denbigh Hall Jcn to just north of the New Platforms. This work will be carried out continuously from 21:00 Friday 24th December through to 07:00 Monday 27th December.

It won't be long now before you'll be dropping Ballast on the Flyover Roads?
