Does anyone here know people, who are definitely familiar with the Croydon
Tramway and may be interested to introduce this to a Hamburgian audience?
German would be great but (educated) English will be widely understood.

I believe there's someone who posts here who would be perfect.

Thanks for your answer. OK, maybe in the UK the official way is successful.
In Germany its better to contact the known enthusiasts.
