RMweb Premium Chamby Posted December 3, 2021 RMweb Premium Share Posted December 3, 2021 12 hours ago, Tony Wright said: I had a phone call the other evening from a widow, asking for my assistance in 'disposing' of her late husband's model railway collection. Her husband had died in August. Though I can't recall him, I must have spoken to him at shows, since he had my card (which his widow then used to get in touch with me). From what she said, his collection was mainly locomotives, and all RTR - Hornby/Bachmann/Oxford/Heljan/etc, all steam-outline and all boxed. The 'problem' was he'd detailed/altered/weathered, etc, all of them, so they were no longer original. Ironically (so it would appear), despite their then being 'more accurate', their resale value (especially to collectors) is then less. Sadly, I told her I did not 'deal' in such things and advised her to contact the second-hand dealers. One hopes she'll get something back. I had a similar situation recently, only in this case the widow had been married to a club member so I helped out. Not being savvy with internet selling platforms, I found the best place to sell such modified loco’s was in clubs. I contacted three different clubs relatively local to me, and after a couple of visits to each, managed to sell the whole collection. Inevitably, some sold quickly and for better prices, the last few for rather less, but the collection made rather more than I had initially anticipated. The club members got items for less than the resellers ask, and the widow got rather more than a reseller would have offered for the collection, plus the knowledge that her deceased husband’s treasured items had gone to fellow modellers who would similarly appreciate them. That said, it is not a task to be undertaken lightly. Every item needed to be thoroughly test run, parts checked and in some cases repaired, then catalogued and assigned a reasonable value, then each item demonstrated to the potential purchasers. Throughout it all, is an awareness of a commitment made and a responsibility to deliver the right outcome. In my case the widow received a four figure sum for which she was very grateful. But I will think carefully about taking on such a task again, given the amount of work involved. 1 1 1 13 Link to post Share on other sites More sharing options...

Atso Posted December 4, 2021 Share Posted December 4, 2021 (edited) On the subject of rough riding on Gresley locomotives, it would seem that, if the (tender) loco didn't have a Cartazzi truck then it would be a rough rider at speed; especially when due to a works visit. I've just finished reading a book on the LNER mogul classes and it seems that crews didn't like running them at speeds. Therefore, when deputising on express passenger duties, mogul crews would attack climbs as hard as possible so that they wouldn't have to rely on fast downhill running to make up time. Pacific crews on the other hand apparently let their locos find their own pace on a climb knowing that they could always make up time on the downhill stretches. From a modelling perspective, I prefer the Gresley aesthetic over other designers (especially Thompson who designed some ungainly Pacifics) - thankfully my loco crews don't complain about anything!

jrg1 Posted December 4, 2021 Share Posted December 4, 2021 Here's my solution to the pony wheel problem. Because of the long wheelbase of the Raven A2, the axle runs in a round tube, itself in a square section tube that is free to move up and down in the frame slots. I utilised Hornby flangeless wheels, to ensure there would be no derailments on curves, and I still need to do final spring adjustment. 7 1 2 Link to post Share on other sites More sharing options...
RMweb Gold Popular Post Iain.d Posted December 4, 2021 RMweb Gold Popular Post Share Posted December 4, 2021 (edited) I‘ve not posted anything for a few weeks but thought I’d just show where I am up to with an LMS D1810 Restaurant First Open I’m building from a Comet / Wizard Kit. Today I did a final build to make sure all the parts would go together prior to the last wash. There was a bit of minor adjustment needed to the interior / roof interface otherwise all went well. Currently the chassis only has 3 buffers, one was too deformed to use so I’ll purchase a replacement pack in the New Year. The roof is detachable, being secured by two 12BA bolts fixed in the roof, I drilled holes in the roof, filed the bolt heads to shape and fixed them in and tidied up with some filler. I soldered in two substantial cross members to the coach sides that the bolts pass through, these improve the rigidity of the body when handling. I’ll add roof rain strips (from tape) after the last wash. The coupling bar I have fabricated hangs down a bit in the assembled image, it won’t on final assembly as I have bent a short piece of wire to act like spring to keep it elevated. I have also made up all the handrails, scissor gangways, cut the windows, etc. I’ll knock up some curtains through the week. And I’ll paint the interior and fix in the tables too. The lamps are a length of .5mm wire with a short piece of semi-transparent wire sheathing to represent the shades. It’s now at the point of painting, tomorrow morning I’ll try and get a coat of grey Tamiya primer on the roof and body and Vallejo Surface primer on the chassis (German Panzer grey with and some brown primer added). I’ll spray in the garage, which is currently at 25 degrees, hopefully it’ll cool down to below 20 tonight!!

I am not sure that the LNER mogul classes were ever designed for high speed running, so it is hardly a shock that they were not smooth runners when they were trying to perform duties that would normally require a pacific or suchlike. I think most 2-6-0 designs would have been the same running at express speeds on top link duties. The fact that locos like the K3s were able to perform such duties when needed to deputise for a proper express loco at all is more of a positive than a negative. I don't think it is any surprise that the vast majority of top link express locos from all companies, certainly post 1923, had a bogie at the front. Honourable exceptions being the V2 and the P2 and they were not immune from problems with their leading pony trucks. When the mogul types were kept on the duties they were intended for, they performed well, especially the K3s and the K4s. 5 3 Link to post Share on other sites More sharing options...

I'm tempted to imagine that if there's any freedom at all for those wheels to descend to, or below, normal railhead level, then (bearing in mind that no track I've ever seen is dead level everywhere) there will be a risk of them getting alongside rather than on top of the rails on curves, and then fighting the loco's attempts to run straight after the curve. I worry that a twitchy / jerky rear end action, or a derailment of other wheelsets might result.

60526 Posted December 4, 2021 Share Posted December 4, 2021 Tony, There I was enjoying a nice pint of Black Sheep listening to the BRM panel discussion between Phil Parker, Chris Mead, Graham Nicholas and yourself, when I choked somewhat, I thought that I heard you say that "weathering should not be used to disguise mistakes". A quick reverse and yes you did say that. Now, the other day I was looking at buying one of the Hornby A2's, it would have been the most expensive RTR model that I have ever bought,model costs have caught up with me somewhat, I'd previously decided not to spend that sort of money on a model which I consider has the wrong colour green. I can understand you waxing lyrical about some of the newer Hornby models in the BRM videos, I'd agree the B1 is particularly good, but do you really believe that the A2 out of the box is the right coloured green? I'm not totally convinced, but the weathered A2 you have shown photos of seems to cover it up some what? Charlie 2 Link to post Share on other sites More sharing options...

John The Hornby WC is the easiest. I'd guess that it was designed with a pivoting truck, but changed to a fixed truck with flangeless wheels. If only all Pacifics were designed that way - modding to pivoting trucks with flanged wheels would be a doddle! John Isherwood. 1 Link to post Share on other sites More sharing options...

I had the same thoughts but it makes sense to me if the set up is rigidly bolted to the bottom of the frames, rather than mounted on a pivot, so it has vertical springing but no side to side movement. 1 1 Link to post Share on other sites More sharing options...
