Travelling through Northern France to-day, it is interesting to see British locomotives of various types working our military trains. In the 1914–1918 conflict, British Army locomotives bearing on their tender sides the letters “R.O.D.” (Railway Operating Division) were a common sight on the French lines, and to-day our engines are again assisting the French locomotive departments. In general, the same transportation procedure is being followed in handling our Army traffic in France as in 1914–1918. Certain routes, where our traffic predominates, have been taken over entirely by the Army, while in other cases Britain merely supplies locomotives and rolling-stock and leaves the operating to our French colleagues. Our R.T.Os. are at work at all important stations, maintaining the closest touch with the local railway officials. Actually, the British locomotives operating over the French lines to-day bear the letters “W.D.,” instead of the old familiar “R.O.D.,” and they comprise machines of varying types, among which are many of the 2–8–0 and 0–6–0 wheel arrangements. In addition to the engines supplied by the Home railways, the Government has placed contracts with leading builders for the supply of 240 2–8–0 type freight tender locomotives and 10,000 20-ton covered goods wagons for service in France.
