I'll post in English, seeing as how my German is rustier than a Barry hulk...
Following Gordon's post on http://www.rmweb.co.uk I thought I'd have a look at your site. You never know, from time to time I might be able to help you with queries.
I have three main modelling interests: Deutsche Bundesbahn in the late 1970s/early 1980s (Wuppertal area), British Railways late 1960s (North West, LNWR/L&Y area) and Network SouthEast third rail area late 1980s/early 1990s "Sectorisation era", also featuring parcels, Railfreight Distribution and InterCity sector trains. I've also dabbled in Irish railway modelling, but it's very much a side interest.
I presently live in Cheshire, and have two websites with railway photographs from Britain and Ireland- see signature.
Better than Manchester, I'm close to Crewe and the West Coast Main Line!
I'm doing OK on my Wuppertal research. I'm planning a layout based on Wuppertal-Cronenberg, and have found plenty of good material. I'm stopping off in Wuppertal on my way to the Czech republic in May- we're picking up the night train there.
