With the topic of the International Technical IPWE Seminar, held 12&13th January 2017 at Mumbai:
“Challenges in Design and Maintenance of Track under Mixed Traffic Regime of Semi High-Speed and heavy Axle-Load”
an invitation to the ingenuity of Indian`s Track Experts had been launched to come forward with technical solutions, how the different track-structure requirements for Freight-Train Axle-Load Increase and Passenger-Train Speed Increase can be compiled and how this ambiguous programme can be technically achieved on India`s busy rail-corridors.
Between the lines of some presented Technical Papers, one can read that some experts are NOT so happy with the ambiguous concept of a compiled programme to increase the Axle-Load of Freight-Trains up to 25 t under a “Mixed Traffic-Regime” on on-and-the-same-route of Indian Railway`s conventional track structures simultaneously with the deployment of higher Speed Passenger-Trains running up to 160 kmph.
Measurements to improve operational flexibility without simultaneous Axle-Load and Train-Speed Increase are not yet fully out-bidden. There is still room on IR to increase the transport-capacity and to reduce the journey-time of passenger-trains between major cities, resp. to speed up intercity-links, before IR has to push ahead for a MIXED TRAFFIC-REGIME with higher Axle-Load simultaneously with Semi High-Speed – a costly SIMULTANEOUS PROGRAMME, the implementation of it will become long-term highly Capital-Investment intensive.
The question, Semi High-Speed YES or NOT on India`s busy corridors, is not under dispute. It is disputed, if it is prudent to combine on India`s busy rail-corridors Freight-Train Axle-Load Increase with the Passenger-Train Speed Increase. The message is to increase Train-Speed gradually without simultaneous Axle-Load Increase.
