(I must have missed it somewhere above.) I don't have, and have never read, Langridge's book. I was merely saying that he was correct to attribute problems with the 4F axleboxes to inappropriate lubrication, as has been analysed by Adrian Tester, A Defence of the Midland/LMS Class 4 0-6-0 (1911). The Derby drawing office certainly understood axlebox lubrication - lubricants had been R.M. Deeley's special subject. Problems arose when the LMS changed the formula of the standard lubricant (cost being a consideration, I believe). The issue was identified and remedied but not without it entering enthusiasts' mythology, thanks to the writings of ex-LMS personnel with axes to grind. I think we've seen quite enough in recent years to show that people will generally prefer lurid fantasy to sober fact. 1 2 1 1 Link to post Share on other sites More sharing options...
Popular Post LNER4479 Posted March 29, 2021 Author Popular Post Share Posted March 29, 2021 (edited) No trains this evening, I'm afraid; rather a report on electrical work and an invitation to comment on control panel design (for those whose boats are floated by such things). Work is complete - for now - at 'grand junction' in terms of reconfiguring the wiring for remote operation. A closer look, showing wiring brought to these terminal blocks. The relay panel deals with the frog switching, leaving the other half of double micro-switches on the points to deal with point indication - these wires are fed straight to the terminal blocks for communication to the control panel. Yet again, another good 'ol H&M product provides power for now, the direct 16vAC and 12vDC outputs being perfect for the CDU and relay panel power inputs respectively. Approx 15 feet away, here's the Bog Junction control panel starting to take shape. The Gaugemaster D panel unit is at the heart of the structure; above this I've mounted what is intended as a miniature instrument shelf. And these views show a mock up to give a more complete idea. The idea is that all this will be behind the backscene, running at a relatively modest height of 9ins above baseboard level. On the equipment shelf will be 7 miniature block bell indicators for communication with the next section along the various routes. By some distance, this will be the most complex control position on the layout in terms of communication with other boxes. Below the instrument shelf is the track diagram, which will be illuminated to show what routes are set - at the right hand end are the points at Grand Junction which will be the first to be illuminated, using the wiring already installed. To the left of the diagram goes the lever frame (on order) for Bog Junction. Beneath will be the bank of relays which will deal with the logic. On the opposite (right hand) side of the controller are the terminals for all the incoming wiring. As there is likely to be a lot(!) I've included provision for approx 100 - you can see the first bank being the other end of the connections from 'grand junction'. The idea is that the dial indicator switches on the block indicators, as well as giving the 'line clear' and 'train on line' indications, will do clever things via the relay panels to prove the route (in conjunction with the locking information from the lever frame) and connect up power to the track. Any comments / observations gratefully received. I tend to be a bit ill-disciplined when it comes to wiring and control systems - not so much 'make it up as I go along'; more a case of gradual evolution as I start to do bits and the thing starts to crystallise in my mind. But I do want it to be based on traditional mechanical signalling and the use of block instruments does have considerable appeal to me. There is an early opportunity to prototype that aspect by installing a corresponding clock instrument at Garsdale.

I'll just make one comment - how about reversing the positions of the block shelf and diagram? Then the block instruments will be closer to the controller and lever frame, so you won't have to wave your arms around so much, while the illuminated diagram will be closer to your eye line. 1 2 1 Link to post Share on other sites More sharing options...

Then the block instruments will be closer to the controller and lever frame, so you won't have to wave your arms around so much, while the illuminated diagram will be closer to your eye line. That would be nice; unfortunately, I have to leave space for the lever frame and that has to go to the left hand side of where the track diagram currently is. It will be a true mechanical frame, ie direct mechanical connection to points and signals. I am slightly stuck awaiting its arrival to be sure of exact size and position. Also, although miniature, I need to make the block instruments as large as I can as they will have a rotating switch, bell tapper and indicator lights (dials would be nice!) all in a small space. I just don't think there would be enough room for them all where the diagram currently is. It's probably the least satisfactory aspect of the arrangement but overall it doesn't feel too bad and I do like the feel of the instrument shelf above the lever frame (left hand side). Thanks for providing at least one constructive suggestion (although I never mind a bit of humour!) 3 2 Link to post Share on other sites More sharing options...
