Much easier just to hand build your fiddle yard turnouts since you are going to do that for the scenic areas. Fiddle yard turnouts are a quicker build as you can cut the number of timbers by half or more, and a substantial saving over those expensive Peco points as well. Or go for 00SF in the scenic areas to avoid all that fiddling with widening back to backs.

Yes, of course and the report explains that. That was when the points tried to normalise, what is not covered, not even to say that the investigation could not determine the cause, was why the points failed to normalise when originally called to set the route. A number of reasons are possible and had the wiring been correct would have not been an issue. Had the redrive on detection failure not derailed the train things could have been worse, the indication in the report is that the driver noticed he had been wrongly diverted but did not appear in any hurry to apply the brakes.

Correspondence testing could have been done to the KRs without a signalman, but maybe that would have needed a higher grade of tester? But the whole thing was sloppy, pre-installation checks missed it, the installers wirecount missed it, the tester just forgot to do the correspondence test and apparently even ticking the relevant boxes on the form did not remind him. And it was indeed very lucky that it was a test train that found it after several months of the fault waiting to manifest itself. Nothing in the report to give any reason that the A end chose that move to fail to normalise.

And the Tanganyika railway was started when it was a German colony, so something of a coincidence that the EAR was all metre gauge. And later EAR steam locos and wagons were built for easy conversion to 3'6" ready for when they linked up to the then Rhodesia Railways. But by the time TAZARA made the link it was to late for the steamers and the gauge conversion has not been done and is now unlikely with Kenya going over to Standard Gauge.

I suspect just the torsion bar linkage, visible on the photos.

I think it means you tap in on the reader on the bus, hence the comment about people getting off.

Those look like Romford/Markits wheels. Are you sure you measured the crank throw properly? 3.5 mm is only 10.5 inches in 4mm scale and a rather small throw.

There are a few pics of catch points out there, here's one. https://www.pinterest.co.uk/pin/817544138575596481/

On what do you base that assumption? I would expect UP to have investigators who would have attended. And there were obviously a large work crew there who managed to get to a pretty remote site. Someone pretty senior had to be there to decide on who and what to call out. But certainly a private vertically integrated and fraight only railroad would have a lot less beaurocracy than we have here.

The idea of the Pennsy signal heads was to replicate the semaphore aspects with white lights so giving the same indications by day and night and eliminating any worry about colourblindness. Hence the heads were arranged to give a row of 3 lamps horizontal for stop, at 45 degrees for caution and vertical for clear. The B&O version modified this by omitting the central lamp so that it became rows of two with the verticals green, the 45 degrees yellow and the horizontals red. Google will find more details easily enough.

That does not look like any Tesla wheel. I suspect the photo and the story are unconnected.

Yes, but rab is using DC and hence has to solve the reverse loop problem, not specifically scissors related a simple crossover would have the same problem. Not so bad if you always run through the reverse loops the same way, feed the loop through a bridge rectifier and reverse the controller while in the loop. But really you have to look at the whole layout wiring and control system. Looking at the scissors in isolation only works for DCC.

It doesn't protect the sidings, it protects the running line from the sidings.

Charles 3rd has been officially announced as his choice.

Well the problem areas are going to be the crossing flangeways and checkrail settings on the points and possibly the switchblade as well. Rather than splashing out on driving wheels and likely wasting your cash, first get hold of a pair of P4 wagon or coach wheels and see it you can find a back to back setting that will work.

I note the video claiming that carrying away spoil by rain is "removing" lots of lorries from London's roads. I see a big difference between "removing" and "not adding". The spoil lorries were not there to be removed.

Then at least answer the question I asked here, about terminus or through station and we can draw the plan!

When you say, "how ground signals work" do you mean the mechanics or the operational function? The former is pretty obvious, the lever pulls the wire, the signal goes to proceed, restore the lever the balance weight pulls the wire back and the signal goes to stop. The latter is probably best explained by examples, if you post your track plan we can add signals to it with explanations.

If you are modelling the 20th century then point indicators would be very rare, shunt signals were the norm. Lots of variations depending on company and the rotating variety are much easier to model working than others, especially if you don't mind the balance weight being dummy since all you need then is a vertical spindle through the board that can rotate 90 degrees. Drive easily arranged by crank and wire or a direct drive from a servo spindle. Query, is it a terminus or a through station? It makes quite a difference to the signalling and we can't quite see what happens to the main track at the near end in the photo.

Given its for an H0 model and I don't think modellers had laser cutters in 1979, piecing saw and files were more the thing or a milling machine. It may not give all of the protoyype fine details but I think it does provide what the OP was asking. I could supply the whole article on request.

Repeater certainly, its a crank operated circuit controller and you can see the cable.

Here is a drawing of a 2-8-0 frame which might give a clearer picture. Model Railroader that month, Sept 1972, had a blow by blow article on how to build it.

About two trains a week!

Then you don't need the trap point in the passenger line but you do need one on the exit from the creamery. Trap points are required to protect passenger lines from goods lines or sidings, but not required in passenger lines. Shame when its so nicely modelled that it is in the wrong place.
