"TRB's Transportation Research Record: Journal of the Transportation Research Board, No. 2374 consists of 22 papers that explore high-speed rail network design and station location; the competitiveness of high-speed rail; the economic impacts of Amtrak intercity service; an evaluation of high-speed rail corridors; the impacts of short-term land use by high-speed rail on large metropolises; and high-speed rail train scheduling. This issue of the TRR also examines dynamic wheel loads of high-speed; railway operational disruption predictions; periodic railway timetabling problems; human performance in railway operations; rail operating costs models; strategies for rail transport of hazardous materials; the capacity of single- and double-track rail lines; the use of recycled tire rubber to modify track-substructure interaction; ballast shear strength from large-scale triaxial tests; track stiffness transition zones; and rail transit optimization models. TRR 2374 also addresses in situ measurement of neutral temperature in continuous-welded rail; ultrasonic tomography for three-dimensional imaging of internal rail flaws; the characterization of railroad ballast behavior under repeated loading; aggregate properties that influence railroad ballast performance; the measurement of rail seat pressure distribution in concrete crossties." -- pub. desc.
