I'd agree with that. My rough calculation is an overall radius of around 48". It has to be a rough calculation, because it is not a smooth curve. The section through the frog is noticeably flatter than the rest.

Having called them Large Radius though, they will be stuck for a name if they do any bigger ones Ginormous, megalarge?????

Hornby may have caught on to a great way of making model liveries more prototypical there - paint the real thing the same as the model ;)

Ideally, we need a full range of diamond crossing(s) 3-way, slips and larger radius points to make a decent layout. How to go about building that one piece of track that you need, but PECO will never ever supply though? Commercial chairs like C&L look quite large compared to the Peco bullhead ones. I am just wondering if you could cannibalise the Peco track to make your own, but am probably not brave enough to try.

Looks a bit Beyer Peacock to me. The loco bit could probably be disguised as one of their products.

The 1864 OS map suggests an elaborate frontage something like the print - but it is little more than a curtain wall. The main offices are along the north side, parallel with Lord Nelson Street. Maybe both were from the same era? https://www.old-maps.co.uk/#/Map/335042/390561/13/101757

There was an article in the HMRS Journal Vol 14 no 10 about secondhand coaches. It has this to say re the NLR. - all 4-wheelers, earliest 3rds had one window between doors. The M&GN had 28 vehicles. It has a photo of an IoW 3rd vehicle with double doors in the middle - presumably adapted by the IoW Rly as a brake coach, so adaptations could and did happen. Best bet I reckon that the Norwich vehicle would originally have been a composite with single windows between the doors in 3rd class - and maybe adapted by the M&GN or whatever? Of course, we might even have the possibility of 2 vehicles being joined together to make the hut.............

This photo on the Chacewater site shows some Easingwold Rly ex-NLR coaches. The middle one appears to be a composite with single windows between the doors at the far end - just to illustrate that they weren't all the same. Unfortunately I don't know much about the M&GN and its constituents. It might even have altered carriages to suit its needs - like adding luggage compartments, for example?

Now you are being awkward! Unfortunately, I know next to nothing about NLR coaches. The panelling above the windows does appear to have shadow at the bottom rather than at the top though, suggesting it projects out like the photo of the NLR coach. To my knowledge, that is pretty well unique to the NLR. The First in my photo above has a double door luggage compartment, so there must have been a few variations on the theme. We probably need a North London Railway carriage expert to intervene at this stage.

Apparently there were devastating floods in East Anglia in 1912 - might account for the changes on the subsequent OS map, including the disappearance of the coach. I have a copy of Clark's History of M&GN Locomotives. This shows a similar grounded NLR coach on p72 at Yarmouth Beach.

Me too!

This foto on the Furness Railway Trust site shows the kind of panelling I mean The Norwich body is probably not another one of that particular coach, but a very distinctive style so probably another ex-NLR vehicle or combination thereof.

Bingo? Old North London Railway coaches had relatively large oblong windows, rectangular shaped ventilators above the door windows and rounded panelling above the other windows. Some were definitely sold to the E&M or predecessors. Pity we can't see below window level, as the panelling was quite distinctive.

Just wondering if the coach could be ex-North London Railway. Some 4-wheelers were bought secondhand for use on what became the M&GN. These had square cornered windows.

Sorry to repeat myself, but I think there is no way that coach is sitting on the track. It has to be a body sitting at the side of the river 1. Looking at the photo, the top of the coach roof is no higher than the top of the coal truck, which can't be if it is on wheels, because... 2. all the tracks in the loco shed area appear on maps to be at the same level 3. The maps suggest a coach-shaped building next to the river 4. Why park a through coach at the loco shed, which is some way from the station. there are many sidings much closer to the station that are likely to be used for carriage servicing etc. 5. The very odd mix of panelling and windows suggests something very unusual. The rounded panels could possibly be just painted on to make an old coach look modern. 6. There is possibly a large stovepipe chimney sticking out of the roof - notice just above the coal wagon. I think it is an old coach body that has been grounded and tarted up. Either a mess hut for railway employees, or maybe a fishing hut, as it is right next to the river.

Another thought that just occurred to me. Why would a through coach from another railway that was (presumably) being sent back whence it came pretty quickly be parked at the back of the loco shed? Norwich City was not exactly short of siding space much nearer the station. Servicing and storage would surely be in the carriage sidings or even in the station area itself?

This is the MS&L style of panelling The coach is now restored in early GC livery

It has been mentioned back beyond somewhere that the MS&L style of panelling had curved edges to the tops of the windows. The coach in the photo clearly has square corners. Also, MS&L livery was varnished wood. The two tone livery was first introduced for the London Extension which was by then GC. I think this is an just old coach that has been grounded and tarted up as a mess room for the loco staff. It is difficult to be sure, but I think the curved panelling above the windows is just painted on. There is no hint of shadow or relief of any kind to suggest real panelling.

I wonder if the coach is actually a grounded body. As has already been pointed out, it is sitting quite low compared to the coal wagon. Looking at the OS map for the era there is something looking suspiciously like a coach body shape, off the rails and in roughly the right place

The 'Longer Tom'

Well, I certainly don't remember reading anything in Genesis about railway mergers, so probably a safe bet

Grouping began almost at the dawn of railways and carried on to a very limited extent even after 1923. Some railways were never grouped at all. Pregrouping is a bad name all round.

There was a very similar design by Thomson Houston running in Paris on suburban duties. Possibly drawings or photos were shared with the British arm of the company?

Nationalisation of our neighbouring railways was rather drawn out. French railways were nationalised in 1938, though some lines were state owned before that. Belgium had a kind of creeping nationalisation, most of which was achieved before WW1. Technically, the Dutch have never nationalised in a technical sense though they heavily supported the construction of the network and gave additional financial support to the railways after WW1, including buying shares. Spain nationalised broad gauge lines immediately after the civil war. Portugal was rather drawn out. Italy was essentially 1905, Denmark 1885. Germany was a State and then a National system, effectively government owned for the most part from the beginning. It didn't all happen at once..
