One of my sons lived in Selsey for some years and on holidays staying with him, I would look around for evidence of the Tramway.
The manager of the North Mundham Light Railway will probably agree that there is precious little left. In fact, the only item visible from the bus, at least, is an abutment where the line crossed the Chichester canal and there are a few places where the levelled ground of a footpath gives a hint of its origin. I'm sure that the local resident, however, can give a more accurate summary.
It had a weird history and, for many years ran illegally without an Act of Parliament. I think this may be the reason why the trackbed was so easily re-claimed on closure, and is difficult to locate.
I think you would probably have to go off-piste a bit to fins any evidence nowadays.
There are one or two good books about it, and it is, indeed a fascinating story.
Oh, just looked at the preface to my book - '............. for most of its life it ran with no legality as a railway at all.'
I think I'm right that, many hundreds of years before the railways, the Bishop's palace was at Selsey rather than Chichester.
We've hi-jacked Peter's thread a bit, but I think the answer with the Simplex trams must be overseas rather than in the UK - possibly a bit nearer Peter than we are
