NACHs Computer Database of the Value of Operational Incidents
Client: London Underground, Nov 1995 - Apr 1996
Many rail operators have only a poor idea of the traffic lost through operational incidents. Moreover, those staff who do know are likely to be based in headquarters, and not able to do much about any particular problem. London Underground, however, wished not only to understand more fully the financial consequences of incidents such as train, power and escalator failures, line and station closures, but also to provide a tool which might help supervisors take the best course of action.
The Railway Consultancy Ltd were therefore commissioned to develop the program of analysis required to provide the information required, and the structure of a database which came to contain 33,000 items of analysis. Consultancy staff were responsible for many of the calculations, using spreadsheets, train service simulations and network modelling techniques. An Access database and special user-friendly 'front end' were subsequently written by LT staff and other consultants, to provide a useful tool which is saving London Transport and its passengers much time and money.
This database is now being used as part of the commercial arrangements underpinning the Public:Private Partnership between London Underground and the InfraCos maintaining the infrastructure.
