The Engineer's Sketch-Book. Thomas Walker Barber

Various forms of four-wheel under-frames, with and without swivelling bogies.

      A car with four wheels arranged as No. 217, but with the leading and trailing wheels slightly raised off the ground, is used as a goods car or hand truck, and is very readily swivelled about, running, of course, actually on three wheels only.

      218. Five-wheel under-frame, with and without swivelling bogies.

219 & 223. Plans of six-wheel cars, with swivelling gear for curves; the centre pair having end play, swivel the leading and trailing axles by means of the jointed stays.

      220. Plan of four-wheel car, with swivelling gear for curves.

221, 222, & 224. Six-wheel cars, the latter with leading and trailing swivelling bogies.

      225. Eight-wheel double-bogie under-frame. This is the plan usually employed in long cars; each bogie is free to swivel independently, and is centrally loaded.

      Larger plate.

226. Ten-wheel double-bogie under frame, the centre pair to have end play or broad flat tyres.

      227. Twelve wheels and three bogies. The centre bogie must have end play, either as in Nos. 222 or 226, or with transverse rollers between the bogie and frame.

      Note that in Nos. 221, 223, & 224 the centre pairs, if running on rails, must have either end play in the bearings or flat broad tyres.

      228. Open passenger car, either with transverse or longitudinal seats.

      229. Covered passenger car, with either longitudinal or transverse seats.

230. Passenger car, with outside and central longitudinal seats.

231. Passenger car, with upper and lower longitudinal seats.

      232. Passenger car, as No. 231, but with seats reversed.

      233. Passenger car, for one-rail railway.

      234. Passenger car, similar to No. 230, but with seats reversed.

      235. American plan of passenger car, with transverse seats and central gangway.

      236. Goods cars, low sided.

      237. Covered or box wagon.

      238. Hopper wagon for discharging below.

      239. Side discharge hopper wagon.

      240. Side tip (or end tip) three-centre wagon.

      241. Tip cart.

      242. Tip wagon.
