For the Walshaerts, perhaps a look through Jeremy's GWR Railmotor topic will help.

Re: Kyle of Lochalsh MPD - track layout

Looks like they were shovelling coal from the wagon direct to the tender rather than using it for ash.

Re: Kyle of Lochalsh MPD - track layout

As far as the correct location for the turout goes it looks different in every photo! Probably why you are asking. :) Mostly it looks around a loco length from the shed, on the photo with the 2-6-4T and the one with two black 5s I would put the switch toes almost opposite the crossing of the turnout...

Re: A4 points out of 6 chain curves

Interestingly on the DLR we had turnout designs with both straight and curved crossings (we called them vees). So the 4 designs specific to DLR were CV40, SV40, CV100 and SV100. For longer turnouts we used standard big railway geometry. CV40 = Curved Vee, 40 m radius. etc. For the most part the CV w...

Re: Kyle of Lochalsh MPD - track layout

Going by what seems to me the age of the various pictures it looks as though the siding was added rather than removed, ie was there in 1960. The coaling stage opposite the water tower serves the turntable road and does not look like it ever moved. On the photo with the platelayers trolley there is a...

Re: Suspension for bogie coaches

Some real things do not have the springs between the axleboxes and bogies. Apparently, American freight cars often have no primary springs, with the axleboxes free-falling in their guides and the secondary suspension doing all the work. I presume that the weight distribution between wheels in a bog...

Re: Tandem turnout length question

The slip in that photo does not have interlaced timbers, I think it would be all but impossible with a double slip. (Cue for someone to produce a photo). It would be pretty difficult with a tandem as well, the chair spacing would be to much with 3 sleepers replacing each timber and packing would be ...

Re: Tandem turnout length question

Its clear enough where the gaps are but the bit round the centre crossing where the timbers are doubled up really does need sorting properly, the shove timbers thing is pretty simple actually. I've done that and then just drawn checkrails in on the printout to save the trouble of drawing them. This ...

Re: Tandem turnout length question

This last photo with levers is certainly more convincing especially as ir shows both levers.
I would sort out the timbers (timber shoving function) before worrying about the check rails.

Re: 3 way turnout length question

I'm trying to get my head round that. There is a three throw at Butterley but this is a three way. Generally both the vee and the switchblade must be supported just like a normal point. Three throw and three way are two ways to describe the same thing, ie where the two sets of blades are colocated....

Re: 3 way turnout length question

i don't think you can expect 100% accuracy from an OS 25" map. So I would be happy with the match you have. You would need a railway track plan to do much better. If you want to get it shorter it should be possible, the switches look rather like C switches, if so try B instead. Oh, and that's a...

What BR database is that? My understanding was that, except for wartime, almost all the 37 stayed on the LTS until electrification. Mass withdrawal was 1962.

Re: Easing wheels tight to gauge

What the back plate is trying to do, if you can actually get one in given the limited clearance behind P4 wheels, is to transfer the force applied by the claws of the tool from the tyre rim to the hub which is the bit you need to move.

Re: Easing wheels tight to gauge

Don't you mean to avoid concentrating the pull on the tyre thus pulling the tyre off?
The screw should be pushing on the axle end not the wheel hub.

Re: Motor Shorting

You say the motor runs when power is applied directly to the terminals, so the motor is basically OK and both terminals cannot be connected to the case. Check connections between the moror terminals and the motor case, neither should be connected. Note that you will need an ohmeter on a low setting ...

Re: Exactoscale wagon chassis kits

I'm with you Guy, those Mk2 spring holders are a nightmare to get right. Both systems were designed to bottom out and only spring downwards, so if you want it to ride on the springs you have to keep the weight down or beef up the spring wire size. I found this a fairly general trait with Exactoscale...

So is your locking intended to match the diagram? Assuming it is, then t...
