Running in

Maria picked up a problem again a few weeks ago but over the last couple of days has put in some hard yardage on extended test runs without any problems. So i don't know what to make of this little blue shunter, i shall give it some more running in and see if the problems can be solved once and for all. The Yellow Peril has also been putting in the shifts, its running in quite well now. I am starting to think about another locomotive though the next change is likely to be Falcon returning in the New Year to replace Jam Sandwich.
