An experiment-based empirical model for heavy-haul train air brake

Controller Design for Heavy-haul Train System

In this paper the existing control methods for train control in the various areas such as energy consumption and travelling time are examined. A closedloop cruise controller to minimise the in-train force in the couplers is proposed. Simulation results for both regulation and disturbance rejection are given.

Optimal Cruise Control of Heavy-haul Train Equipped with Electronic Controlled Pneumatic Brake Systems

In this paper a closed-loop cruise controller to minimise the running costs of the heavy-haul train is proposed. Consideration is given to velocity tracking, intrain force and fuel consumption, as well as optimisation of them. To overcome the communication constraints, a fencing concept is introduced whereby the controller is reconfigured adaptively to the current track topology. Simulation res...

A parametric model of the train delay distribution to improve planning of heavy haul cycle times

Efficient heavy haul operations require accurate predictions of terminal arrival times and equipment cycle times. Most analytical and parametric approaches for railway capacity evaluation and operations planning focus on predicting average train delay and not the performance of individual trains and their delay distribution. In practice, train delay varies about this average according to some d...

Longitudinal Control of Heavy Vehicles with Air Brake Actuation Delays

Effect of train-type heterogeneity on single-track heavy haul railway line capacity

North American heavy haul railroads are experiencing growth in traffic demand and increasingly facing capacity constraints. A key factor influencing railroad operations is heterogeneity in train characteristics. Different train types can have substantially different operating characteristics including maximum speed, power-to-ton ratio and dispatching priority. This heterogeneity causes conflict...
