For all of the bridges uniform moving loads of 4000lb. per linear foot of track were assumed with a con-centrated load of 50,000 lb. on one axle at any Indiana Union Traction Company—Combined Station and Substation at Springport, Ind. ELECTRIC RAILWAY JOURNAL [Vol. XLIII, No. 15. 824 The steel bridges were designed to conform to Coopersspecifications for steel railway bridges.
