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 of the J class, and make sure this isn't some kind of uneasy blend. There's also the problem of dates, since they did have some changes over their lives with the Barry Railway. Its sometimes said that its as easy to get models right as wrong, and presumably the same is said of sketches like mine, but I find it an endless struggle to get a reasonable stab at the details. To say the least its rare to find a set of photographs taken from all angles of a single locomotive on a single date, and even then you'd need dimensioned drawings as well. Also one really needs to become expert on the locomotives of a given railway, and I'm more of a generalist. I'll recommend again the work of the Welsh Railway Research Circle when it comes to studying these locomotives. I was surprised to see more brightwork on the photographs of these than I've sketched for other Barry classes, and I had better go back and check the other passenger types at some stage.
