Fair comment, inspector_blakey.

However, Network Rail are not against trees 'just for the sake of it'. Also from
the BBC» :
Trees planted in Kent after harsh winter
Tens of thousands of trees are being planted across Kent, but later than planned because of the cold winter.
Distribution of 31,000 young saplings under the Kent Free Trees scheme was delayed by two months because of sub-zero ground conditions.
More than 1,000 applications were received from individuals, schools, community groups and landowners, who could apply for up to 25 trees each.
Native species handed out included oak, ash, beech and hazel.
The trees are usually handed out at the beginning of December, but distribution was delayed until this month.
The scheme is sponsored by Kent's borough and district councils, Bexley Council in London, and Network Rail.
