Signalling failure - Portsmouth 16 July 2018

The request was successful.

Dear Network Rail Limited,

I was subject to a delay of an hour due to various train delays/cancellation on 16 July 2018. I understand the cause was a signalling failure in the Portsmouth Harbour area overnight.

I would like to know :

1. The root cause of the failure
2. Whether the potential for this failure was pre-emptively identified?
3. If so, what proactive maintenance was undertaken to minimise the risk of this failure occurring?
4. What steps will National Rail be taking to reduce the risk of the same failure occurring again?

Yours faithfully,

Paul Larner
