The addition to the length of the platform required ad-ditional strength in the side trusses. In consequence, the sidetruss rod was lengthened and the truss was deepened 10 in.

The original cars, of course, were equipped with double slidingend doors with an opening, when open, 34 in. in width. This,of course, was too narrow for a car operated on the prepay-ment plan, and on the first lot of cars two-piece bulkhead doorswere used in which one part slid over the other to provide anopening 47 in. in width. Toward the end of the work of con-verting these 250 cars, a new arrangement was developedwhereby it was possible to use a single door on each side of thecenter line of the bulkhead instead of the two-piece door. This. 6—7—over-Sills Metropolitan Rolling Stock and Shops—Section and Plan Showing Arrangement of Bulkheads and Single-Piece Door in Latest Converted Cars of converting these cars was started in July, 1909, and they werecompleted by the end of December. The cars so altered were some originally built by The J. Company and were of the type of car which had beenStandard on the Metropolitan Street Railway, with only minorchanges, from 1898 to 1906. The cars measured 6 ft. 7 width over the sills, had a 28-ft. body and an over-all length arrangement was installed upon the last car that was convertedof the lot of 250 cars, and is working in a very satisfactorymanner. The design, which has been patented by H. H. Adams,superintendent of rolling stock of the Metropolitan StreetRailway Company, is illustrated in the accompanying engrav-ing.
