Many thanks for the kind words, but your photoshopping of the shot of 60506 beats my effort hands down. Anyway, in the hope of finding a view of LB which won't have been seen before, and in accordance with your request to take something which showed the bit of scenic work I did, I took this. That's a great shot, Gilbert, and one I've never tried before - my camera would squash your scenic work, which is where you've placed yours! Don't Ellen Sparkes' (Andy, The Green Howards' daughter) little gardens look lovely? The M&GNR/MR girder bridge should be finally installed soon. Regarding your 'Photoshopping', don't do yourself down. Where one has telegraph poles and other fiddly bits to isolate, it takes time, and I have a full-professional (if old) programme to use. I also have two highly-computer-literate sons who showed me how to use it! Some of the shots you achieve on Peterborough North are exceptionally-realistic.

grahame Posted January 24, 2020 Share Posted January 24, 2020 Progress has significantly slowed down on my scratch-built Interfrigo wagons project but here's a progress report if anyone is interested. Recently I've only added the handrails and locking bars to all three cast resin bodies I'll be using and given them a coat of gloss white top coat. Currently I'm trying to draw up suitable artwork for print at home decals based on pics of an HO model, the real wagons and some files an RMweb member (Andy acg5324) kindly sent me of those he used for his own Interfrigo wagon project. Hopefully I'll have learnt sufficient to also be able to draw up artwork for having the end platforms/steps and large distinctive handbrake levers etched. This project has become quite a 'have to do everything yourself' effort as there is almost nothing commercially available which has slowed things down. 7 1 6 Link to post Share on other sites More sharing options...

Vauclain scheme 80.43 kB · 0 downloads Are you suggesting that the Webb compounds and the Claughtons were better than what Gresley was doing? Both were short lived and withdrawn or rebuilt after very short working lives. Gresley was a big fan of Chapelon and did introduce some of his ideas and I recall seeing a proposed design of Chapelon inspired 4-8-0 but that never went ahead. I can't remember why. The Compounds were, I think a "near miss" and were capable of some fine performances. The Claughtons were adequate at best. As with many locos, a change in CME meant a change in loco development and the new man in charge is always far more likely to want to introduce his own ideas than keep on doing what his predecessor did. All Gresley needed on the P2 was a different pony truck (the one on the V2 would have done the trick) and a beefier crank axle. Even without them, they did good work for 10 years and would probably have lasted longer (and maybe got a new crank axle and pony truck) had Thompson not replaced Gresley. We will never know.

ecgtheow Posted January 24, 2020 Share Posted January 24, 2020 11 hours ago, Andy Reichert said: One has to wonder what our transportation history would have been like if Micheal Faraday and James Watt had been born in the reverse order. Instead of Steam Punk, the latest Hornby 2020 model announcements would have been for "Electric Victoriana", or something like that. In fact the likelihood of Steam power or even the "Steam Era" ever being introduced as the underlying force of the Industrial Revolution would have been close to zero. Andy Perhaps it would have been like rail transport in Switzerland? The last mainline steam locomotive for the SBB federal railways was built in 1917 (a 2-10-0 which was actually very efficient for its time & lasted until 1968). Thereafter almost all lines were electrified progressively & now Switzerland has the most dense railway network in the world, the greatest distance travelled/ inhabitant (1,528 miles in 2015) & has been ranked first in Europe for intensity of its use, quality of service & safety record. One could go on. All that AND the cost to performance ratios outperform the average for all European countries. The downside of course would be no glorious steam locomotives such as A4, Duchess, Merchant Navy, 9F, etc which the majority of users of this blog including me prefer to remember.

Along with other pre-WW1 systems like the Grimsby and Immingham Electric Railway and the London and South Western Railway suburban lines out of Waterloo. There's a surprising amount of electrified systems, both obsolete and in current use, in the UK including light rail (like the London Docklands Railway and Tyne and Wear Metro) and a big recent increase in urban tram systems like Croydon, Manchester, Sheffield, West Midlands, Edinburgh and Nottingham as well as quite large swathes of electrified main and suburban lines. Unfortunately, although many are historic they don't find a lot a favour for being modelled. Oddly, usually when an electric railway is modelled it is of, or based on, a real electrified line/location rather than a made up fictitious line that is very common layout type for steam and diesel traction. 2 Link to post Share on other sites More sharing options...

This is the unaltered TIF shot as the camera took the picture. After using layers/masks/cloning/sharpening/clarifying, this is the result; slightly cropped from the original. In order to speed up the process, I cloned the 'wall' colour around the telegraph pole, so I didn't have to take the lasso tool around every insulator. That said, it still took 40 minutes to reach this state. What does all this show? You have a very good eye for a picture. Unless the space restrictions are really tight, the big camera can get into the same positions (within physical limits). The depth of field is superior with the big camera (F32), and the images are crisper (might that be expected, given the enormous difference in the camera's prices?). By employing longer exposures, I'm able to use pulses of fill-in flash to pick out detail in shadows. You achieve some splendid results with your small camera Andy York also gets some splendid images with the same camera. Here's another replicated shot. How did the shots come out where I placed your camera on the platforms? That's where I struggle with my Df. Regards, Tony. Good morning Tony, I would have placed a piece of white card at the back of that pesky telegraph pole before pressing the shutter. Out of interest, have you ever experimented with directional lighting and shadows on LB to recreate different times of day? Is that a thing at all in model railways?

RLBH Posted January 24, 2020 Share Posted January 24, 2020 14 hours ago, Bucoops said: Horsepower is power - if Wikipedia is correct the Duchesses were capable of in excess of 2500hp whereas a P2 in excess of 2000hp. Based on cylinder dimensions and boiler pressure, the P2 should be capable of about 7% more power than a Coronation assuming similar steam utilisation. A Coronation should be good for about 2,450hp which is pretty comparable to the 2,511hp achieved by Duchess of Abercorn; a P2 should be good for 2,620hp. I'd suggest that the lack of records of P2s achieving that sort of performance is because they were a small, short-lived fleet with mechanical issues, so nobody ever had a chance to hook up a dynamometer car on one working flat out. 2 Link to post Share on other sites More sharing options...

Good morning Andrew, I don't try to replicate lighting at different times of the day. The room Little Bytham is in is very well-lit with 'daylight' tubes, giving an overall illumination without too many deep shadows. I really just want to photograph a model railway, so consistent (and even) light is essential. Not 'sunlight', which produces too deep a shadow in my view, especially underneath steam-outline loco footplates. Regards, Tony. 1 Link to post Share on other sites More sharing options...

Out of interest, have you ever experimented with directional lighting and shadows on LB to recreate different times of day? Is that a thing at all in model railways? There’s an excellent example at Peco, Dave and Shirley Rowe made a Spanish diorama that changed from high noon to starlit sky including the sunrise and sunset. With individual grain of wheat bulbs for the stars it’s a fascinating and very effective display. @Clive Mortimore may recall an Essex based modeller that used to take a diorama style layout around the Home Counties with variable lighting, using different color lamps and mixing them for effect. The chap used to do theatre lighting which was the lead in to the displays. Lighting layouts effectively is pretty challenging, and many don’t seem to balance the lighting to their layout, meaning their work isn’t shown to its best. I’ve been doing quite a bit of experimenting, Shelfie1 having a variable ‘blue’ light input which has given an improved look, particularly when at Warley when they had the orange overcast lighting a few years back.
