Excavator at work

On the new estate a few miles out of Stratford,  where S and C live, work has started on the next phase of house building. The new houses will be close to the lovely woodland walk we enjoy so this afternoon we watched this machine at work along with a smaller model - it was like a mechanical ballet ! 
Further round the walk is an ex MOD site which has a connection to a railway line and for the last few years I have wondered why there was a collection of railway axles lined up on the tracks - they have now been moved further away from the surrounding fence.
