As an quent stops, it was equally as essential to provide the strongestand most substantial type of car construction throughout. Ahappy solution of the problem seemed to lay in the use of steelcar construction, but the limitations of car building- facilitiesprevented a sufficiently early production in steel at first. Owing to the two essentials of lightest weight consistentwith strength, however, which were embodied in their con-.

After having ascertained the general type of cars whichwould be best adapted for the subway service, and before plac-ing orders, it was decided to build sample cars embodying theapproved principles of design. From these the managementbelieved that the details of construction could be more per-fectly determined than in any other way. Consequently, in theearly part of 1902, two sample cars were built and equippedwith a variety of appliances and furnishings so that the finaltype could be intelligently selected. From the tests conductedon these cars, the final type of car which is described
