Thompson Coaches - a Question of grain

[Trestrol]

Good point, Trestrol! And as for those SIG bogies, the less said the better! BR1s would be an improvement when they were knackered![/quote]

Are you trying to say that the fine GWR BR1 bogie is not the finest design of bogie ever made. You will be telling me next that other railway companies existed apart from the GWR!

I always thought that the BR1 bogie was essentially the LMS design rather than GW?

[Blink Bonny]

Ay up, Trestrol!

Wash your mouth out with soap and water! I was brought up LMS / LNER and am a fan of those lines, with a smattering of things Bullied. Green, Wet and Rusty? Took an LNWR man to sort out the boiler!

The BR1 was pretty good and I thought was an amalgam of LMS / GWR practice. However, when they got worn, they got wild!

[sawdust]

My understanding is that the BR 1 bogie was basically GWR with LMS axleboxes. They were not good enough at speed which was they bought in the expensive cast Commonwealth bogies, I believe? I have always found them noisy and a bit rough.

A little belatedly to this one gents, but if you can find a copy of Jenkinson and Camplng's 'Historic Carriage Drawings' (landscape format) from about 196?, it gives you a good range of drawings of both Gresley and Thompson stock, with all the relevant dimensions. The one which it doesn't - which I am after at the moment - is the Gresley BY four-wheel parcels/pigeon van. Does anyone know the diamater of the bufferheads? I'm building a Chivers 'Finelines' kit at the moment, and the cast buffers they provide are .5-1.0mm too small, and don't look right. Any ideas?

The North Norfolk have a Gresley BY, you could do worse than ask them. I'm sure they will oblige if especially if you grease their tape measure with a small donation.

The more recent 'Historic Carriage Drawings' series published by Pendragon has an increased range of LNER & Constituent drawings in volume 2, by Nick Campling, and some additional van drawings, including the Dia. 120 van that you are making in volume 3, NPCS, by Peter Tatlow. However the diameter of the buffer is not stated.

The best drawings for details are those produced by the late John Edgson under his 'Isinglass' label:http://www.isinglass-models.co.uk/ but his drawing does not give this dimension either.

I believe that the correct diameter is 1' 6".

Ay up!

Sorry to drag this one back up again, but would I be right in thinking that Post War coaches in mock teak livery used the same lettering as Pre-War ones?

Apologies if this seems like a daft question but when it comes to coach modelling I know nowt!

Yes basically. But without the large 3 on third class doors.

Ay up!

Many thanks, Sawdust. Always nice when a hunch proves correct!

[Blink Bonny]

Ay up!

Another daft question: What diameter were the vac reservoirs? The thought of buying castings to make them fails to appeal somehow...

[Dave]

Vac reservoirs were 3'-8" long x 1'-4¼" dia generally althought 3'-6" x 1'-4¼" were under some restaurant cars when mounted along the centre line. The vac cyls were 21" dia. hope this helps.

[Blink Bonny]

Ay up, Dave!

It does indeed. Some 5mm diameter plastic tube or rod about to be purchased. Many thanks!

[Blink Bonny]

Ay up!

I'm confused. During a late night diabetic hypo last night, I gooooooogled Thompson coaches and looked at the images.

The SRPS' TTO seems to have a band of horizontal grain above the windows whereas the LNERCA's subs do not.

This may be my eyes seeing things that aren't there but, assuming I have interpreted the SRPS piccies correctly, which is correct? Or are both correct?

EDIT: Now I'm even more confused because the piccies sent to me by Mike Trice and Coachmann appear to show vertical grain to the cantrail.

I'm off to lie down in a darkened room.....

Out of interest, here is a part copy of LNER drwg 16543N Corridor 3rd Brake of 1945 which shows the so called Thompson bogie.
So far I've not come across any detail drawings for it.

Ay up, Dave!

There are detailed drawings for the "Thompson bogie" and kits for it. Problem is, it was the older Fox bogie and only used under the prototype vehicle.
