Heavy Locomotive and Increased Railway Speed.—The Philadelphia Ledger cites the exhibition in France of a locomotive weighing sixty tons, with ten-feet driving wheels, and stated to be capable of attaining a speed of 100 miles per hour. Its centre of gravity is placed so low as to render it safer than ordinary engines at the usual speed, so far as getting off the track is concerned. The Ledger doubts whether this speed named can be reached without much larger driving wheels, but cannot doubt the practicability of achieving it with larger one; or that by elevating the track so as to allow of a very low centre of gravity, together with widening the space between the rails and avoiding common roads by bridges and tunnels, railroad trains can move with ease and safety 150 miles per hour.
