. The Street railway journal . Balti-more & Ohio Railroad in the city of Baltimore. A briefrestatement of the reasons adopting for electricity in thistunnel will not be out of place. The tunnel, which is the largest soft dirt tunnelever built, extends from the present Camden of the Baltimore & Ohio Railroad, a distance of 7350ft. north under the heart of the city. Beyond the north-ern portal, the Belt Line continues through a series ofshort tunnels and cuts for a distance of about five mileswhere it joins the old main line. The main tunnel hasan up grade of p. c. going north. The heavy workthat would be required of steam locomotives haulingfreight trains up this grade would occasion the filling ofthe tunnel with so much gas and smoke as to .seriously inter-fere with the passenger service. To show how true thisis, it may be said that before the electric locomotives wereput into service a few freight trains were run through thetunnel but the result was that several men were asphyxiated,.

The illustration (Fig. i) gives an idea of the locationof the tunnel and of what its use accomplishes. By itsmeans a reduction of sixteen minutes in the running timeof the Blue Line trains between New York and Wash-ington is now made and it is probable that thissaving will be increased later on. Morever, all dela3-s inwinter due to ice in the river are done away with. Shortly after locomotive No. i had been put intoser\-ice, and had given an exhibition of its ability to haul theheaviest freight trains, it became a matter of general inter-est as to how much it could pull and how fast it could locomotive was, therefore, given a trial at haulingseveral of the passenger trains at high speeds, which it didsatisfactorily to all concerned.
