I'm interested in railway related stuff, usually older and in the UK, but also the newly opening Chinese high-speed railways. I have a special interest in spiral railways and have travelled over a lot of them and I have aspirations to travel a few more yet.
Recently spent some time upgrading depreciated RDTs.
Current longer term projects are a collapsible RDT for the China high-speed railway coastal passageway, and a revision of the article on Camping coaches.
