About this blog

I'm mulling over a supplement to my GWR locomotive development book.
New sketches I prepare will appear here (in small size).  Comments and corrections on the original (be nice!) and suggestions for content in the supplement welcome.
 

If you are planning a model of any of the locomotives featured in this blog you are very welcome to contact me and I'll see if there's anything I can do to assist you in researching for your model.

Barry Railway F Class

The F class was very similar to the A class except for the saddle tank. The F class is one of the trickier ones to sketch out, because there were several different batches from builders, and variations between the batches, front overhang for example, definitely existed. There are two styles of foot plate valance too.  The first five at least had a straight valance, the remainder curved as drawn.      This second sketch shows a lightly swindonised version of the F class, still

Barry Locomotive Sketches

Well, I've covered all the main Barry classes in varying levels of detail as my fancy and my sources permit. The other absorbed lines won't be nearly as simple - the Barry Railway was founded late and had a particularly organised and disciplined locomotive policy. There are some obvious books on the Barry Railway locomotives for those who wish to learn more. My main references have been "The Barry Railway Diagrams and photographs of Locomotives Coaches and Wagons" by Eric R Mountford, Oakwood Pr

Barry Railway E Class

A class of five small lightweight 0-6-0T, numbered 781-5 by the GWR. Two survived to join British Railways but were gone by 1950, whilst three went to industrial use in the 1930s and lasted to 1958/60. Only one received a really major GWR rebuild, which included a non standard Swindon designed boiler as well as GWR style cab and bunker.  There are complexities around the E class bunkers! 781, 783 and 785 had an upward extension of the bunker with coal plates in Barry days, but 782 and 784 d

Barry Railway C Class

Built by Sharp Stewart, the C class originally comprised four small 2-4-0T, without the standard boiler used by most Barry Railway classes. In 1898 two were converted to 2-4-2T, and the other two, one also converted to 2-4-2T, were sold to the Port Talbot Railway. Both the Barry locomotives were gone by 1928, even though one received a major rebuild with a Metro boiler.     

Barry Railway L Class

These ten locos, built in 1914, discarded the old Barry standards and were a bigger loco overall with a much bigger boiler and a very large bunker. They were generally considered successful with the exception of a serious and strange flaw. When running forwards the rear coupled wheels had a tendency to switch points as they passed through them, sending the trailing bogie down the other branch. In reverse, they were fine. Naturally this resulted in an immediate derailment, and this was usually co

Barry Railway K Class

This first sketch is aimed at being post war, but pre grouping.   In 1899, the Barry railway desperately needed some new locomotives, but all British builders were at full capacity. To resolve this, the five locomotives of the K class was ordered from Cooke Loco and Machine Co in the USA. It seems the Barry railway really wanted something as close as possible to the B1 class and the Americans wanted to build something as close as possible to their standard product. The result was a dec

Barry Railway D Class

I've rather struggled with this one. There were only four of them, and they were all built by one builder. How difficult can it be? Well, one source of confusion was that I had 4 drawings, one Barry weight diagram, two GWR weight diagrams and a distorted photo of a drawing by Trefor L. Jones, whose work is generally excellent, but I think may have been struggling with some of the same issues. They were contradictions all over the place. I also had few photos, and all of those were front 3/4 view

Barry Railway J Class

The J Class. Another fairly early version of this sketch. Interesting to compare the J class 2-4-2T with the G Class 0-4-4T. They both use the standard Barry boiler and cylinders, but the J is a longer and heavier locomotive with considerably more coal and water capacity. Sadly I don't know enough about locomotive design to understand the pros and cons of the 0-4-4 and 2-4-2 wheel arrangements. I need to focus a bit more on the differences between the Sharp, Stewart and Hudswell Clarke versions

Barry Railway H Class

This is a early version sketch of a Barry H class. There are some puzzles. Photos appear to show a much narrower dome than the various weight diagrams, Barry and GW, which I've tried to reproduce. More problems come from the underframe being in shadows on most photographs. No brakes shoes on the leading driving wheel, and although I've drawn them the same, I have a suspicion the brake gear on the second pair of drivers was different to the other two. Finally the best profile shot of the L/H side
