A surprise find at Horsham this afternoon was the usual Darlington based MMT unit, DR97501/601/801. Aside from having travelled some 300 miles since the last sighting a week today, of note is that from RTT it has been travelling under headcodes of other units. It appears to have moved from Darlington to Chaddersden, and hence to Horsham under headcode 6U84 and in the past few nights has been working around Lancing/Hove under headcode 6U88 (which is the code for the usually Horsham based 97508 etc).
Not sure how long it will remain at Horsham but it may be of interest given it seldom has left the North East.
