Trees near rail line at Clovis Duveau Drive

Some weeks ago, on behalf of residents in the Clovis Duveau Drive area, I contacted Network Rail about the overgrown trees and foliage from their ground between the rail line at the nearby houses.
I have now had the following positive response from Network Rail :
“Please accept my apologies for the delay in contacting you regarding this matter.
I have attached photographs which were taken … after completion of the work – that shows the trees and vegetation situated on our land near to the properties concerned –  which include trees, cultivated hedges and plants present on the housing side – and all provide a screen from the operational railway.
It is essential that this vegetation is properly controlled and managed.  For this reason, Network Rail carries out a nationwide, planned programme of vegetation management throughout the year.” 
The photo (above right) shows the area with the trees thinned back.
