From small-scale timetable changes such as those associated with new stations and infrastructure change to the introduction of significant change accompanying the implementation of national-level programmes, Ed Jeffery offers timetable development and planning using a variety of tools and software packages (RailSys/ ATTune).
Ed Jeffery can provide an end-to-end service during your scheme development process to support the development of infrastructure schemes as they progress through each stage.
Timetable development and performance modelling can be used to assess the benefits of different options such as journey time, capacity, or performance to help option selection, refine options under development or input into a business case. This can be on an ad-hoc basis when services are required, or a long-term contractual basis to ensure consistency throughout the process.
Performance modelling using specialist software (RailSys) can help build an improved timetable and analyse the benefits of an infrastructure or timetable change. It can help answer questions such as whether your change positively or negatively impacts network performance and evaluates different options to help select the most beneficial.
Ed Jeffery can simulate the operation of a timetable on a typical day using real-world delay data and perform scenario modelling to look at the impact of events on the operation of the network. Our performance modelling reports can help inform your decision-making process and build your business cases through concept to delivery.
Ed Jeffery uses various software to deliver highly detailed simulation and modelling outputs to our clients. These include:
Timetable development: simulation of a timetable can help build a better timetable by detecting and eliminating conflicts.
Calculation of timetable planning rules for infrastructure or rolling stock changes.
Calculation of sectional running times (SRTs) to help build a case for line speed improvements or new rolling stock.
Performance modelling to validate outputs against more comprehensive network performance.
Capacity analysis to define a future strategy or look at individual enhancements to realise benefits.
In addition to schemes that are already in the development process, we have a lot of experience working at longer-term timescales for long-term strategic planning. This helps set the industry strategy and feeds into the industry regulatory process (such as Periodic Review and the Long-Term Planning Process).
