چکیده
In light of the improvements to capacity and timeliness heavy-haul railway transportation that can be organized through group trains originating at a technical station, we address train operation scheduling problem with freight demand importance via newly proposed mixed integer programming model simulated annealing algorithm. The optimization objective is minimize weighted sum cost total cargo travel time under condition matching supply within period. main constraints are extracted from relations, delivery commitment, maintenance time, number locomotives. A algorithm was constructed generate grouping scheme, stopping scheme running schedule trains. numerical experiment based on real configuration employed verify efficacy heuristics results show methodology achieve high-quality solutions. case reveal volume increased by 2.03%, departure decreased CNY 337,000, which difference in 27,764, 40.9%, indicating create benefits for both enterprises customers.

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.
متن کاملEffect 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...
متن کاملMathematical Solutions for Solving Periodic Railway Transportation
Train scheduling has been a significant issue in the railway industry. Over the last few years, numerous approaches and tools have been developed to compute railway scheduling. In this paper, we present a set of heuristics for a constraint-based train scheduling tool, which is a project in collaboration with the National Network of Spanish Railways RENFE , Spain. We formulate train scheduling a...
متن کاملAustenitic Manganese Steels – Developments for Heavy Haul Rail Transportation
In 1882, Sir Thomas Hadfield patented an alloy with quite remarkable properties. Its composition was Fe-1.3%C-13%Mn and it was the toughest alloy known! The claim has stuck for the century since then and the alloy is now used universally for the “frog” in railway crossings in countries such as Canada where heavy loads are moved by rail using high axle loading. In fact, the alloy is very soft wh...
