Network Rail greenwash?

Much greenwash from Network Rail over the long awaited works to the 'Poacher line':

Passengers on the Boston to Skegness line are set to benefit from a £21m injection of new track on the route. The overall project will see 32 miles of track replaced using recycled materials making the railways even greener.

How much greener it would be if the rails and sleepers had been recycled, as used to be the case, instead of reusable rail being sliced up into 10m lengths for removal by road..

Green?

Perhaps a pale tint of eau de nil!
