The number of cable thefts from railways in Berkshire has doubled over the past year.
In 2009/2010 there were 8 incidents, this year the number is 18.
Throughout this week British Transport Police have been carrying out "nights of action" to target the problem.
Superintendent Paul Brogden is from BTP and has been on operation overnight so BBC Radio Berkshire's David Prever asked if it had been a success..
You may remember last summer 100 metres of cable was taken from West Drayton - causing hours of delays on the trains between Reading and Paddington.
People were telling BBC Radio Berkshire how they were stuck on the trains for hours whilst the problem was sorted.
Mike Greedy is from Passenger Focus and told David how frustrating this can be.
Clive Owen is the general manager of A1 Metal Recycling in Wokingham. David asked him how much you can get for copper at the moment.
