This LNER B1 locomotive was re-built at Loughborough and had its first
run
after re-building, on 28 March 1997 - photos here, and its first
main line steam run from Hellifield to Carlisle on 9 June 1999. Photos here.
More information on locomotive 61264 is here, and here, and here.
Your nearest steam railway to experience the real thing is at Brockford Station.

A bit fuzzy because it's a very small section of a large photo, as the loco was quite a distance from the photographer.

After these photos were published, I received this email from someone who was on the train at the time the photos were taken:
"The trip was organised by a company called The Rail Touring Company http://www.railwaytouring.co.uk/ that specialise in running vintage steam excursions on main lines throughout the UK, and rail-based holidays abroad.
As far as I know, this trip was open to the public, although it's possible a coach may have been block booked by a club such as the one you mention. Alternatively, and more likely, it was just a recreation to the sort of thing that used to happen regularly in the 50s and 60s when 'rail enthusiast clubs' would hire trains for railtours.
I believe the run was the first occasion that a steam hauled train has passed down the East Suffolk line since the official end of steam in the mid 1960s (though someone may know otherwise!). As I'm sure you know, [no, I didn't - ed] Thompson B1 class locomotives were commonly used in the East Anglian region, so the locomotive was a very appropriate choice. The pace of the run was a little more leisurely than the trains of today but for the most part matched the timetabling of the steam era. A friend of mine had a GPS unit, which showed that the train exceeded 70mph at times, reaching a maximum speed of around 75mph near Manningtree. Not bad for a machine over 50 years old, hauling a heavy train!
All in all, a grand day out!
Best wishes
