The Editors asked if I would put together some notes on inside cylindered 0−4−0 tank locomotives. By leaving geared and jackshaft-drive types to another time the task is simplified. It is not easy to give reasons for the small number built since these reasons do not apply when six−coupled tanks are considered. As far as is known Beyer Peacock built the most (mainly for Dowlais Ironworks), followed by Peckett with at least nine. Walker of Wigan would possibly come third with about six. Barclay specimens still exist at Llanelly Steel Company (1907) Ltd., and there was one by Hudswell Clarke at the South Wales Steelworks (later Richard Thomas & Baldwins) also in Llanelly. Bagnall's built several in their early days; the designer put the cylinders between the axles with the drive on to the front axle, but this made for a long wheelbase and consequent unpopularity. Hunslet built three for the narrow gauge (640 of 1895 for Southchurch Brickfields Ltd., Southend; 641 of 1895 for British Plate Glass Co Ltd., St Helens - actually a 2−2−0 saddle tank; 764 of 1902 for Brundrit & Co Ltd., Penmaenmawr - illustrated in the new North Wales Pocket Book F) but none for the standard gauge that I know of. Having briefly covered the major builders we are left with odd examples by I. W. Boulton, Butterley Company, Dowlais Ironworks, Hawthorns (of Leith), Neilson (crane tanks), and Platt Bros (of Oldham). E. B. Wilson and Sharp Stewart built a few in the dark ages, Tennant (of Newington) constructed Lothian Coal Company 3, and PORTOBELLO of the New British Iron Company was built at the Coven Works (Staffs) of John Smith. Rowntree & Company (of York) had one, supposedly by Manning Wardle, and finally we are left with those locomotives by makers unknown. One of these was the oddity at the Preston Docks depot of Thos. W. Ward Ltd which came from Sheffield; it should be within the living memory of older enthusiasts. I make the usual plea for correspondence on omissions, etc.

The photograph above illustrates the mystery locomotive at Preston Docks.

    [Below] Peckett 1107 (class Y) was supplied new to the Derwent Steel Works, Workington, of Cammell, Laird & Co Ltd on 11th December 1906; she acquired side tanks in her later days and spent most of her working life at the Lowca Colliery where she was scrapped in April 1966. Dowlais Ironworks 40 KING GEORGE V, built at Dowlais in 1907, was designed by G. Robson who had main line connections, hence its general appearance and Belpaire firebox.

    This photograph, from the collection of Alan Brotchie, is captioned "Pug used for building second Tay Bridge" for the North British Railway. We wonder whether this "pug" was built by Andrew Barclay or some other Scottish builder. Do our experts know?
