Mitigating train-type heterogeneity on a single-track line
North American railroads are experiencing growth in traffic demand and increasingly need to expand capacity on their lines; this will require changes in the mode of operation and infrastructure. Infrastructure expansion requires long lead times and is capital-intensive. Alternatively, some additional capacity may be achieved by alteration of the mode of operation which is often less expensive a...
متن کاملA turn-back track constraint train scheduling algorithm on a multi-interval rail transit line
With the rapid increase of passenger volume, the interval of some rail transit lines in China has reached a minimum value, which makes turn-back capacity one of the main capacity-limiting factors instead of section headway, particularly during the peak hours on workdays. A general simulation modeling framework and algorithm in which the divide and conquer rule is adopted for train scheduling pr...
متن کاملOn Train Track Splitting Sequences
We present a structure theorem for the subsurface projections of train track splitting sequences. For the proof we introduce induced tracks, efficient position, and wide curves. As a consequence of the structure theorem we prove that train track sliding and splitting sequences give quasi-geodesics in the train track graph; this generalizes a result of Hamenstädt [Invent. Math.].
متن کاملOptimal Scheduling of Trains on a Single Line Track
This paper describes the development and use of a model designed to optimise train schedules on single line rail corridors. The model has been developed with two major applications in mind, namely: as a decision support tool for train dispatchers to schedule trains in real time in an optimal way; and as a planning tool to evaluate the impact of timetable changes, as well as railroad infrastruct...
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...
