LTK’s simulation capability includes detailed single train (“TPC”) type simulations, multiple train rail network simulations for operational evaluation as well as traction power simulation. As transit agencies and rail networks with electric train operations strive to reduce both consumption and peak demand, LTK’s Operations Analysis & Simulation professionals can model the best energy-saving strategies. Our simulations can include strategic coasting, reduced throttle position/tractive effort, per-car and per-train current limits, deployment of energy storage devices and/or regenerative braking – all of which can make the already “green” rail mode even greener. Our Vehicle Engineering staff is recognized experts in determining the feasibility of retrofitting regenerative braking capability into older rail fleets.
Where scheduled rail operations are approaching (or, sometimes, exceeding) the practical capacity of the rail network at maximum scheduled speed, network operations simulation is a valuable tool to assess the reliability of an existing or proposed operation. LTK’s software tools support this type of analysis, which is often performed under both “deterministic” (no variability in performance of equipment or behavior of train crews and passengers) and “stochastic” (variability or randomization that produces differences in each simulation run despite identical inputs) conditions.
