Re: LMS/LNWR 1930s junction distant signalling

That article at least gives the date when installation of colour light distants started so you can forget about them if you are in the 30s. Note that the use of 'mechanically operated' is a bit of a misnomer, the signals themselves are normal colour lights (searchlights were also tried). I think the...

Re: LMS/LNWR 1930s junction distant signalling

Like most phasing out, a very long process, changes would only be made if the location concerned had significant work underway. On main lines such as the WCML the LMS had a policy for upgrades and renewals to the block system that involved installation of colour light distants so as that took effect...

Re: LMS/LNWR 1930s junction distant signalling

Must be a mighty big layout if you have room for the distants. :) I would think it likely that it would have worked splitting distants, suggest looking up a few WCML signal boxes on the SRS or Signalbox.org sites to confirm, they must have some. I don't know if the LNW went in for fixed distants at ...

re Exactoscale fastrack concrete sleeper bases.
The stores listing shows:

Am I correct that BH here is a typo and should be FB?

Re: MTK class 59 kit - Let the challenge commence.

Essentially the inner chassis will have to replicate many features of the Bachmann cast frame in order to correctly accept the bogies and provide suitable mounting for the motor, so will inevitably be fairly complex, a horizontal sheet is not going to hack it.

Sundeala had a reputation for sagging 50 years ago although not as bad as 'insulation board' which I once used as it was cheaper. I wouldn't touch either now.

The important thing is to ensure that the magnet does not pull down the two couplings at the same time, uncoupling requires one to be pulled down while the other stays up.

Essentially just what was recommended in the original P4 instructions 55 years ago. :)

And two of them will have drive rods to make sure the blades stay in line when moved.
However with the relatively higher stiffness of model blades you can probably manage with one driv, synching two drives would be difficult.

Re: Turnout construction - Question here please.

Follow the prototype, make your switch so it sits fully against the stock rail naturally without any forcing, assemble it like that. Then the tie bars pull it away to open it rather than pushing to close it.

Re: MR INTERLACED TURNOUTS

The original P4 templates included 3-way points as well as Tandems, but none with interlaced sleepers.
I think the drawings available from NERA include turnouts with interlaced sleepers for the North Eastern.

Re: MR INTERLACED TURNOUTS

You need to distinguish between 3-way turnouts and Tandem turnouts. 3 way turnouts have the two sets of blades superimposed and of a special design, they were common on the MR and on the GER but only in yards. Tandem turnouts have thw two sets of blades seperated so one starts at the heel of the oth...

John, Are you confusing web with foot here? I've never known a stock rail have the web ground back, it would have a serious effect on the strength and serve no purpose anyway.

Re: Mystery through carriage from Cambridge to Cumbria

But earlier, Neil, you said you were looking for a service that started in July 1914.
So this service running in 1910 is a different one? Or the July 1914 date was wrong?
Or the service was suspended then resumed? Or was seasonal?
