Re: Sharman Wheels in P4

OK if you are confident that there will be no need to adjust the quartering after pressing the wheels on.

Re: Kyle of Lochalsh signalling

I would say that the existence of splitting distants makes it clear that there is a running route into the up platform, as well as the junction home signal!

Re: Converted Bachmann Mk1 coaches for 'The Devonian'

1950s [and at least the early 1960s] timetables included Saturdays as weekdays, only Sundays had reduced services. There were some SX trains, but the Devonian ran Monday to Saturday. In my 1964 timetable there are three sections, Mon-Fri, Saturday only and Sunday. The Devonian only appears in the M...

Re: Converted Bachmann Mk1 coaches for 'The Devonian'

Just for a little variation I have a 1964 timetable and the Devonian timings seem to have changed. It is booked out of Bradford at 10:35 am, Newton Abbot 6:25pm, reaching Paignton at 6:53pm and Plymouth at 7:23pm. It specifies RC, MB and TC Bradford to Paignton. The return is 9:15am from Plymouth (6...

Re: Alternative to Templot source

But track chairs are hand soldered or glued to timbers by simple eyeball and hands on methods and then optionally adjusted later by indirectly checking a with a track gauge to the rail head. That is not how its done, the chairs are glued or soldered with the gauges in place and holding the rail, no...

Re: Alternative to Templot source

I was interested if someone else had used a jig method to position and fix the rail support chairs directly onto individual sleepers/timbers. Exactoscale {Bernard Weller) did a system essentially as you describe many years ago, fine if you want to make a lot of similar turnouts but not so good if a...

Re: Contrate and pinion gears

In the case of Fig 29 we show how a tender can be close-coupled on one pivot only to the locomotive, However fig 29 does not actually show that. :) I suspect that the unstated assumptions may be elsewhere in his book, probably where he discusses hanging the tender on the back of the loco for additi...

The article in MRJ 71 by Martin Goodall describes planning his layout and laying out curves etc using the pencil and paper with versines and/or tables off offsets just as we had to do back before we had computer programs capable of doing the hard work.

Re: Track building after 40 years hiatus

As for Templot i just cannot see how to use it to create templates or plan the trackwork. So that is a non starter. Have you tried the tutorials on the Templot forum? They are very clear and step by step. And a simple straight turnout template is only half a dozen clicks most of which are choosing ...

Re: Stopping at an Inner Home signal

Quite remarkable really, if it had been a single line there wouldn't have been a staff for movements within station limits.
Or can you think of an example for that too?

Re: Recreating a Facing Point Lock via electronic locking...

MERG kit PMP27 does this, each deals with 4 servo controls which can be on different Servo4s so use them for the facing points that need locking both ways and rewire the levers for those points to use the SPDT momentary contacts, still use the FPL lever to supply power to the point lever, then locke...

Re: Recreating a Facing Point Lock via electronic locking...

We have an already developed circuit within MERG to convert a servo4 to work with pulses for both directions of movement, that would probably be the simplest way.
I'll look up the relevant info later.

Might be a fixed distant depending on company practice at the time concerned, you can't extrapolate from recent GW practice.

Re: Stopping at an Inner Home signal

But if the train sees the home off as soon as it comes into view he is likely to assume that he has been cleared through and accelerate again then be caught out by the starter being on. This being the scenario that rule 39A is intended to prevent.

Re: Stopping at an Inner Home signal

Rule 39a is not about checking trains it's about not lowering signals in advance of the arrival of the train where a clear run through into the section in advance is not signalled. If there is a clear run through into the section in Advance then signals are pulled off before the train arrives. IMHO...

Re: Stopping at an Inner Home signal

I'm also a bit puzzled by a rule requiring a train to be brought (almost) to a stand after its entry into the forward section has been accepted by the block post in advance. Subjecting the driver of a loose coupled train whose vehicles may be strung out over a 'sawtooth' gradient profile to such a ...

Re: Stopping at an Inner Home signal

It was a new requirement in 1902. Indeed looking more closely at my 1892/1902 document the last sentence covering not ending in a single line was added in 1902. I rather presume that there must have been some sort of incident concerning a train held outside a terminus awaiting the clearance of the ...

Re: Stopping at an Inner Home signal

There was no mention of this requirement in the first BOT requirements in 1858 but by 1902 it was included so somewhere in the intervening 44 years someone thought it a good idea. I've no idea if there are any records anywhere showing the development of the requirements over that period.

Re: Stopping at an Inner Home signal

No mention of platforms in that sentence but the platform comes in an earlier sentence in requirement 11 which says that on double lines each line must have its own platform. Interestingly by 1928 the wording is slightly modified as at terminal stations a double line of railway must not, as a rule ,...

Re: Stopping at an Inner Home signal

In the video, when the goods train stops it is described as a home, when the passenger train proceeds through it is described as an inner home. The link below should take you to the passenger train segment. A bit of mis-captioning then. There is only the one home on the layout, and it was the goods...

Re: Stopping at an Inner Home signal

Most likely rule 39A was in operation. ie for the goods the starter was at stop, for the passenger clear. Now I've looked at the video, firstly the station is a terminus, hence no starter, hence rule 39A is not strictly applicable, the signal concerned is described as home, not inner home and there...
