So after slicing up a Double Engine (above), why am I now mutilating poor old Linda? She‘s a Roundhouse Engineering Mk1 live steam model, given to me 16 years ago by my wife. She’s been a superb performer - gutsy, loud and reliable - with a lovely Lightlines paint job by the late Geoff Munday. Here is a blurred still from a video of her pulling 14 heavy WHR and FR bogie cars with ease (part of a challenge from my brother to see what she was capable of hauling):
But if you’ve read the first page of this thread, you’ll understand why I’ve always wanted her to be Blanche. There’s something about Blanche - a former FR General Manager has described her as a much-loved little green rocket, the current GM called her the FR’s Engine of the Year a couple of seasons ago, while Paul Martin of EDM Models (a regular driver of Blanche) refers to her in his blog as his ‘other woman’. If you haven’t yet felt the unique magic of this strange-looking 2-4-0STT, try this video of a footplate ride
. The American who filmed it describes the experience as the most exhilarating footplate ride he’d had anywhere, and the second half (where Blanche is unleashed on main valve regulator with a full load on the line beyond Penrhyn) is just fabulous.
But turning Linda into Blanche isn’t a simple matter. There‘s a totally different tender, cab and cylinders to begin with. And then there’s the awkward matter of the Roundhouse model portraying Linda in the 1960s - as Nigel says above, in 1972, Blanche was fitted with extended front frames, a longer smokebox to accommodate superheating and a pony truck. There were a few more issues as well:
1. Roundhouse made Linda as a gauge-adjustable model, so the frames are set further apart to accommodate 45mm gauge wheel sets, which has in turn made the bodywork too wide, with proportions adjusted to match. They did a good job of this, but when I finally found an accurate plan, I realised that while the other general dimensions are pretty close, the width is out by a full 10mm (just like the otherwise lovely Accucraft NGG16 Garratt).
2. As far as I can tell, there are no accurate published plans of Blanche in post-1972 condition (I would love to be corrected about this). There is one widely available drawing, but it is poorly drafted and doesn’t even show the extended front frames and smokebox at all. I did, however, have a 16mm scale plan of Linda in original condition drafted by Hunslet’s own Don Townsley and published 50-odd years ago in Model Railways, and this gave me some useful data, such as the correct depth of the chunky red axle cranks (5.5mm, rather than Roundhouse’s anaemic 3mm).
3. There is no room for the pony truck - the space is taken up by the cylinder valves and exhaust piping. The pony truck should have a 1’ diameter wheel (originally taken from one of the long-withdrawn Single Fairlies), so I would need around 20mm of headroom (to allow for flanges and vertical movement) - on my Linda, there is a maximum of 7mm at the lowest point, which is, of course, directly where the pony truck axle needs to go.
4. Lastly, there are plenty of people who know a great deal more about Blanche from first-hand experience than I do, including our own Nigel (James Spooner), Simon D and others, so taking the big step of applying saws, knives, soldering torch and files to one of my nicest, best performing locomotives seemed like too big a risk…….
…..until I took a close look at the smokebox door last summer and saw flaking, bubbling paint. When I looked even more closely, I saw that the smokebox door had also begun to distort, leaving an air gap which would have crippled the steaming of a real Stephensonian steam loco. So I had to dismantle the smokebox and remove the door for repairs. Which promptly fell apart in my hands:

I don’t know whether this failure was caused by mazac rot (which it looks like to me) or by excessive heat over the years (despite the presence of a factory-fitted stainless steel heat shield behind the door), but either way it was a goner. So the big question arose: do I take the lazy route and simply ask Roundhouse for a replacement casting, or do I use this as the opportunity for a proper rebuild so that I could finally have my miniature Blanche…..
