. Book of the Royal blue . CIT 19 ml, but also for a distance of 7, 3yd feetin the open air. As Baltimore is built upon a veryundulating surface there are naturallysome steep grades in the track, and afreight train of forty cars would have tobe pulled by at least two steam engines, using about all the power they couldcommand. It is a common occurrence to sec alout; freight train of about 1, 500 tonnagewaiting to be transported through thecity by way of the tunnel with one ofthese locomotives which can command General Electric Company, at Schenec-tady, N. V., and a brief description ofthem will be interesting. They are made to run in either di-rection, and rival in weight and size thelargest steam locomotive. They aresymmetrical and even handsome in ap-pearance to the eye of the most criticalengineer, and are free from the series ofhumps which are necessary on the backof a steam locomotive. They are notplaythings, as the following dimensionsshow: Number of trucks, 2: weight ondriving wheels, 192, 000 pounds; number. more than double the power of a steamlocomotive. The electric locomotivewill couple on to these trains and pullthem apparently without effort over allthe steep grades. The engineers of thesteam locomotives are required to shutoff all coal gases as they approach thetunnel, consequently the air is kept pure.All passenger trains of six or more carsin length are forbidden to use the tun-nel unless taken through by one of themotor engines. The work of building these ponder-ous machines was supervised by the of driving wheels, 8; draw bar pull, 42, -000 pounds; starting draw bar pull, 60, -000 pounds; gauge, 4 feet 8J2 inches;diameter of drivers, 62 inches inside oftires; length over all, 35 feet; height totop of cab, 14 feet 3 inches: extremewidth, 9 feet 6 4 inches. Should the locomotive be dividedthrough the center of the cab therewould be two distinct individual locomo-tives to all outward appearances, such istheir symmetrical construction.
