I travelled on two heritage railways a couple of weeks ago whilst in East Anglia.
The first was the Nene Valley Railway, which was a little complicated to arrange, but worked out well in the end. The complication was that although I could board a train at Peterborough, I couldn't book from there to Wansford. I had to pay on arrival and use a dedicated coach for the whole journey, which seemed to be to be a bit odd, but it did work. Most of the activity is at Wansford, where the model railway and the cafe but not the shop (although there was a "pop-up" version was open. I wanted to visit Railworld next door, but I didn't have enough time.
The other railway was the North Norfolk, which although it was a fairly long journey from Cambridge (where I was staying) was an absolute delight. The access to the platform at Sheringham was controlled, but everyone was very helpful and pointed out what had to be done and where. I travelled both ways in a dedicated compartment in one of the Gresley Quad Art Sets, which I hadn't used before, and they were excellent. I just did an out and back trip to Holt, but this was enough and I thoroughly enjoyed myself.
A third place I visited was not strictly a heritage railway, but it does have a lot of railway interest. This was Bressingham Steam and Gardens, where there are three narrow gauge lines and a length of standard gauge track. Two of the former were operating, but not the latter - in fact, I don't think that this operates very often, although I may be mistaken. The admission price included trips on the two railways, and I took these, and also walked around the site a couple of times seeing what was there. One of the non-railway attractions is the official "Dad's Army" Collection, which brought back a few memories! Things seemed to be quite relaxed, although the usual precautions needed to be taken, and it's a very good place to visit.
All of these visits went very well (as did some to other, non-railway, places, and showed what can be achieved when things are planned properly. Sadly, I'm now locked down in Newport (as is everyone else here), so there'll be no more trips until that's resolved ... fingers crossed, it won't be for long, but I don't know when things will change.
