Trains in war-time will not travel with passengers in complete darkness if measures used in a test made during the "black-out" at Portsmouth are generally adopted, states the "Daily Telegraph and Morning Post.
Mr. Geoffrey Lloyd, M.P. Parliamentary Under-Secretary for the Home Office, described the test at a meeting in Birmingham recently.
The Southern Railway, he said, arranged for a train to be specially darkened. Instead of having the blinds pulled down, the carriages were fitted with blue lights and a cheap special fitting.
The result of this test, and of previous tests of these lights and fittings, made it fairly certain that trains could be made invisible from a comparatively low altitude, while at the same time giving the passengers sufficient light in which to read and see where they were going.
Mr. Lloyd said that the exercise at Portsmouth showed a great increase in the efficiency of all concerned, and even though much larger numbers were taking part than in the test made last year, the whole operation ran smoothly.
