NR^» (Network Rail - home page) state that the Doublebois Embankment between Bodmin Parkway and Liskeard, needs 'renewal'. It's to be done in the next workplan period.

• investing over £93m repairing or renewing more than 2,300
individual earthwork structures like embankments and
cuttings, including renewing Doublebois embankment in
Cornwall and renewing Kelston Park embankment
near Bath

This sounds a major task requiring an extensive possession to complete. Does anyone here know more of the extent and scope that this work will involve?

Because of the soil conditions here there have been major embankment works in Wiltshire and Berkshire Oxfordshire sections of the mainline between Didcot to Chippenham and from Swindon to Bristol Parkway for many years.  These have not involved complete reconstruction of the embankments but widening them so that the slopes of shallower and occasionally putting some sort of low retaining wall at the bottom of the embankment.   

Unless the problems in Cornwall are radically different I would imaging we are talking about similar solutions.
