Why should disruptions unsettle your operations?

1. Be proactive: Prepare for uncertainty

2. Use KPI-based replanning to keep your trains running

The insights delivered in this briefing are based on the latest research into intelligent disruption management. The practices suggested are designed to increase your responsiveness, and improve the punctuality, reliability and efficiency of your operations.

Disruptions are inevitable. Significantly disrupted services aren’t. Read on to discover how you can manage disruptions swiftly and effectively – and take your punctuality rates to new heights.

Four insights

It’s easy to say you should build slack into your timetables. The challenge lies in doing this strategically.

Having a planning tool which explores what-if scenarios is invaluable. By simulating the effects of various disruptions, you develop a feel for where to place spare capacity in the form of:

•Extraturnaroundtimeforrollingstock–soyoucanabsorb delays and allow sufficient time for support activities such as maintenance and shunting

•Reservedutiesforcrew–tominimizethechancesofhaving your crew caught on the wrong side of a track blockage

Use simulations to explore the trade-off between cost-efficiency and robustness.

Of course you should stick as closely as possible to published schedules. Once again, this is easier said than done.

When even a minor disruption can have hundreds of consequences, planners need immediate insight into which services to adapt and which to cancel.

Give planners immediate insight into the effect of their replanning based on KPIs – before those decisions are implemented.

All changes to operational plans should be coordinated with the infrastructure manager, and communicated immediately to personnel who will be affected by them. It’s also crucial to be able to receive up-to-the-minute feedback on issues such as the availability of resources and the effects of operational changes.

Keep track of which decisions have been communicated, and to whom.

4. Keep everyone on the same page
