Intercity Rail Services from Sydney (Central) to Lithgow Part 2 Reducing end-to-end run-times for intercity rail services on the Western Sydney & Blue Mountains Rail Line to Lithgow This part of Assignment 2 is worth 10% of your total grade for subject 48370 This part of the assignment asks you to undertake some calculations and to make an evaluation of what could be done to improve the customer service and operational efficiency of intercity heavy rail services that connect Lithgow to the various city centres located in Greater Sydney. To do this, you will need to apply what you have learnt about how end-to-end run-times affect service timetables and rolling stock allocation in the tutorials for Part A At present, Intercity services from Central to Lithgow have an end-to-end run-time of 2 hrs and 47 mins for all stops services through the Blue Mountains with limited stops through Sydney and operate at two hourly frequencies throughout the day, with additional services in morning and evening peak periods To begin your evaluation, il services were to be reconfigured so that all intercity services that terminate at Mt Victoria were extended to terminate at Lithgow 1. Calculate the number of train sets and operating crews needed to operate the half hourly intercity service from Central to Mt Victoria with an end-to-end run-time of 2 hours and 22 minutes (1 mark) 2. Now calculate the reduction in end-to-end run-times needed to reduce the number of train sets needed by 1 and 2 respectively (2 Marks) 3. If 30 min intercity services were extended from Mt Victoria to Lithgow, how many train sets and operating crews would be needed to service the route if runtimes between Central and Mt Victoria were reduced as calculated in question 27 (2 Marks) 4. What would be an optimum for more optimum) way forward for extending regular intercity services from Mt Victoria to Lithgow (s Marks) One of the key rail lines that serves Sydney is the Western Sydney Rail Line (WSRL) that connects Sydney's Centralstation with Parramatta, Blacktown and Penrith. The same line also supports Intercity rail services that travel beyond Penrith to Katoomba in the Blue Mountains before terminating at Mt Victoria (which is a small Village in the Blue Mountains). Some intercity services also travel to Lithgow, which is the point in the Western Rail Line where electrification finishes, meaning that only diesel powered train sets can travel beyond this point to Bathurst, Orange and beyond. It has been suggested that a more optimum ways to operate these services would be to have them terminate and turn around at Lithgow, which is a more substantial regional centre.
