There are a few ways, a car rubber mat can sometimes give a stone or brick effect, or some plastic moulding that suits. These would need to be glued to the form and cut to shape before that. The other option is to laboriously cut out each stone in the form. Best to accept a Concrete Bob version with no stone work, much simpler but do not underestimate the strength needed in the mould, nor the weight. Mike thought we could mould it elswhere and lift it in, well 10 of us may have but the risk of breakage would have been high, these things can take a few weeks to fully cure but mould can be removed after a day or three.
Having competed one last year for my friend it would have been very tricky without access to the other side but I guess could be done with some planning and screwed central cross beams. Have a look at this link which describes my friends on from post 1.
I have a very good friend that lives in Somerset and have helped him over the years with his varying Garden Railways, not least in demolishing 2 or them. Hopefully this latest one will get completed as it is in his retirement home and a super start has already been made by both he and his lady...

Jon,
Did you know that some of the very early viaducts Concrete Bob built in Scotland were brick faced because people of the time didn't trust that concrete was strong enough, so he put a brick facing on the viaduct to say it was strengthening them, when in actual fact it was purely for show and he was probably laughing at folk.
Thank you for the link, that is one link I wont be sharing with my wife, My beloved is already struggling to imagine what I have planned and I think that link would tip her over the edge, but thanks, its does have some good ideas.
I work in the construction business and I have witnessed people not listening to what they have been told when erecting shuttering, once the concrete pour starts theirs no going back, only stopping, having a cry then starting again, a few dwag bars will be borrowed from a contractor me thinks.
It's all schienenkönig fault for sharing the pictures of his
tramway anyhow and giving me ideas, I knew we should have moved to somewhere with a bigger garden
Car mats eh, we use something like that but much bigger in the entrance to our offices, I wonder if they would notice 1) if I borrowed one over a weekend and 2) the concrete spall when I returned it, or 3) if I could get away with a permanent relocation of said mat??? The problem is when obscure things go missing they have a bad habit of asking me if I know where an item could be first. But that has definitely got the thinking juices flowing, thanks.

F1 form work, told him what its for and he asked how much support timber I'll need and to be care with the mould oil because the can is open, one of the steel fixers has already asked what shape I need the 16mm bars, all ethically declared to my boss who just thinks I'm one of the worst people for scrounging he has ever met and also told me I can't be borrowing the contractors small lorry again, but who cares, no me, I just need to borrow a small plant trailer
