On Saturday 4th May 2002 it was used on a number of Liverpool St to Shenfield runs. It did some other work on the Monday aswell (bank holiday). There was also a steam hauled service from Liverpool St to Norwich and back both days (that was a railtour though, not normal service). I had a run on it on the Saturday, and I was very impressed with how nice it was. I've just uploaded some pictures to my fotopic site, and they can be found at

It was also supposed to do a run later in the year, in connection with the Harwich sea festival, but this was when the transformer failed, so it was unable to work. For me, it turned out to be a right cock up, due to delays getting to Manningtree (I was delayed on MML, the Underground and FGE), only to find the 306 not running and the 312 running in it's place not going anywhere due to lacking a guard. IIRC it was over an hour before it left (all that time waiting around on a very hot day), so I didn't even get to see more than the end of the sea festival. I then ended up on a packed 321 back from Manningtree to London (the 306 was supposed to run through to London after the festival, but the 312 couldn't since it was needed for the Harwich service), and then had even more delays on MML, along with a packed train with no air-con in half the coaches.
I've just put some Videos on YouTube aswell. They are on a digital camera, so arn't that good (remember, they were taken nearly 5 years ago), but arn't too bad. They might take a little to finish processing.
