RMweb Gold rodent279 Posted April 30, 2021 RMweb Gold Share Posted April 30, 2021 (edited) If my surmise is right about the quins being required for air braking, and the MK1 to translate between coupling types, with a through air pipe, then it would still be fail-safe, as if the temporary brake pipe parted or failed, or the couplings parted, the brakes on the quins and the loco would still come on. It's an unusual arrangement though, as the MK1 would be effectively "unfitted", going against what I understand as the usual arrangement, whereby an unfitted vehicle would be marshalled behind the fitted vehicles. I wonder if special authorisation had to be given for this, and whether the test runs were done with the road blocked to other traffic?

RMweb Premium Compound2632 Posted April 30, 2021 RMweb Premium Share Posted April 30, 2021 I suppose there's also the point that Mk 1s were valuable new carriages whereas the quint-arts were getting on a bit, quite possibly "spare". 1 2 Link to post Share on other sites More sharing options...

BernardTPM Posted April 30, 2021 Share Posted April 30, 2021 2 hours ago, PhilJ W said: By then the locomotives had been delivered to Australia so its origin is a bit of a mystery. In other pics of the same train the carriage doors are open and several people in civvies are standing around it so its obviously been used for carrying the engineers. That's why I said possibly, as DEL7-14 weren't in service until 1955. That batch of coaches were delivered between some time after January 1955 and October 1956, but it seems that test was in February 1954 so although it is a Mk.1 TO (or TTO) it couldn't have been one of the BRCW batch. 1 1 Link to post Share on other sites More sharing options...

According to the Vintage Carriage Trust carriage survey, BRCW had built some mk1 corridor second's in 1953, so not impossible that it was one of those. Or just a spare MK1 rustled up from Tyseley or elsewhere? Edited May 1, 2021 by rodent279 1 1 Link to post Share on other sites More sharing options...
BernardTPM Posted May 1, 2021 Share Posted May 1, 2021 Corridor Thirds (pre-1956, so not yet called Seconds) have different roof vents, which are visible in the photo, so it definitely isn't one of those. Also the coach in the test was said to be a 'saloon'. If someone can find a better reproduction with the number visible we could find out if it was a Third Open (2+1 seating) or Tourist Third Open (2+2 seating). Given it included invited guests I suspect it would be the former rather than the latter. Through air-piping was specially added for the test. 3 Link to post Share on other sites More sharing options...

Yes I'm sure there was some discussion of EE locos on the MSW lines somewhere at some point. I wonder if the result would have a more typical British EE styling to fit the loading gauge? Another use for all those 37s displaced by the forthcoming Accurascale model perhaps, along with the early build EE 1500hp type 3s. Hi, Winter 1991/92, Phil Atkins wrote in Railways South East on page 18: “During last 18 months of Maunsell's tenure Percy Bollen produced alternative designs for electric locomotives in Bo-Bo, 1-Bo Bo-1, 1A-Bo-A1 and Bo-Bo-Bo configurations”. Did anybody ever see at least one of these diagrams? Maybe some technical data? Regards, The Signal Box Cat 1 Link to post Share on other sites More sharing options...

relaxinghobby Posted May 2, 2021 Share Posted May 2, 2021 Big Steam. It's all be done before, imagineering and discussing the types of locomotives that could have been. In this case to carried on improving the timings of West Coat trains between Glasgow and London. How to get more power than and haulage traction than the last big loco the Coronation class pacifics. From 1971 The Railway Magazine page 83 and O.S. Nock's article on improved west coast steam superpower. This example uses a post 1940's King type boiler, eight coupled wheels, a streamline casing and a large eight wheeled tender to avoid having to use pickup water troughs at speed. It comes with a good pedigree of imagination of practical locomotive men who worked in the age of steam. 5 2 Link to post Share on other sites More sharing options...

I think blue large logo would suit an F7, or for that matter, an SD40, and quite a few other North American types. BR Green might work on a GP9-but they look a bit like a class 15 after being coached by the East German shot put team! Edit-this is a GP9, for those who were wondering.

BernardTPM Posted May 2, 2021 Share Posted May 2, 2021 Here's why an F7 wouldn't get very far - Class 47 and F7 end elevations to the same scale: It's also why the body of a Class 59 looks so squashed and elongated. 3 1 Link to post Share on other sites More sharing options...
JimC Posted May 2, 2021 Share Posted May 2, 2021 (edited) Its an interesting observation that the F7 elevation above isn't far off the GWR broad gauge. Same height, but 8 inches narrower. It would be rather close on the roof corners though. Edited May 2, 2021 by JimC 2 Link to post Share on other sites More sharing options...

BernardTPM Posted May 2, 2021 Share Posted May 2, 2021 It's why 00 exists, basically. In real life if you try to fit the same traction equipment in a 7/8 size body you end up redesigning the whole thing. 1 2 Link to post Share on other sites More sharing options...

Funnily enough, you used to be able to buy an F7 in BR blue while Lone Star did one that was in a fictional version of BR green. 1 1 3 Link to post Share on other sites More sharing options...
