Thanks for the additional information. I suppose that if statistics on track incidents (people, fires, etc.) are being compiled, and costs savings determined, then it will be shown that the PEDs reduce incidents and therefore make savings (perhaps based on the PPP NACH tables).
If a separate calculation is made based on delays caused by failures of the doors then this will show increased costs (as platforms without PEDs won't suffer these problems).
It would be interesting to know if both calculations use the same 'cost' model for delays. southernrover - do your reports offset the costs of PED failures against the savings from reduced track incidents?
Thanks.
