The new build version of the Lynton and Barnstaple (UK) Baldwin built narrow gauge 2-4-2T appears to be making good progress now, with assembly currently underway.

Details (updated monthly) can be found on the groups website in the link below...

Latest photos of the construction show it looking like a recogniseable loco now....

As the "King" (i.e. - Elvis) would say, "Verra niiiice!"

Lyn looks like it's going to be "SPECTACULAR"!!!


Sincerely,
Glenn

This has been a very interesting project to follow. It's all been designed with computer aided design (CAD), they've used several innovative fabrication methods, and the locomotive incorporates superheating, the Gas Producer Combustion System (GPCS) and a Lempor exhaust.

I'm looking forward to seeing videos of it in service.

I'm sure it will serve very well despite the use of a computer in the design. I'm also impressed.......

Ha! Dave, you'll be pleased to know that they recently ran into a minor snag when an equalizer didn't fit like it was supposed to during a trial boiler installation. Apparently some adjustment with a flame hatchet was required.

Good - back to real railroading.

December update posted from the group. Trial assembly of most parts was successfully accomplished last month. Read about it here: http://762club.com/762lynformation47.php

Photo showing the assembled locomotive.

One interesting feature that can be seen above is the welded fabrication of the cylinders. They're fitted with piston valves (the original Lyn had slide valves), but they're arranged so they can be camouflaged to look like the originals.

Wow, that machine qualifies as a work of art. What a beautiful fabrication.

She's a little jewel!

How do the Brits manage these things, but we seem to be stuck all the time?

A comment about those cylinders--I can't find any photos on line, but in one of the late Al Staufer's books--Pennsy Power III--there are pix of fabricated cylinders for PRR M1 locomotives. The implication was the welded cylinders were cheaper and lighter than their cast counterparts.

The other thing that came to mind, about how the piston valves will be disguised to look like slide valves, made me think of the Economy piston valve conversions that were available for slide valve engines. Two that wear those today are Nevada Northern's 40 and 93.

Well there's the 2-8-0s on the Georgetown loop that have them as well... And if memory serves B&M 1455 got rather boxy-looking piston valves retrofitted while in service.

Yep, she has the conversion kit, too!

I wonder how many other preserved locomotives have them besides the ones mentioned so far?

This pic was posted in an earlier thread on the Georgetown Loop 2-8-0s; it's not as good as I would like, but it shows Nevada Northern 40 in the shop, with the covers off the valves, showing the construction of the conversion kit.

The new-build Atlantic loco 'Beachy Head' at the Bluebell Railway (UK) also has fabricated cylinders and should be running sometime late next year or early 2019. Some years ago when B.R. Standard Mogul 76079 on the North Yorks Moors Rly cracked a cylinder a replacement was fabricated but never used - due to distortion IIRC. Instead a traditional cast one was made and fitted. Several locos in the U.K. (not all new-builds) have received new cylinders in recent years using castings from both traditional wooden patterns and the new 'disposable' poly-patterns.
