Umm, tunnels with tracks in them? Harz Mountains, miners, in the 15th century

 >Electric Underground Railway

Hmm. What about Siemens in Berlin and Ganz in Budapest? As I recall, the
District Line in London was built using some Ganz technology.

>Television (and PAL)

Apart from Nipkow (1895, Russia:scanning disk), Deeckman & Glage ( 1906, USA,
cathode ray tube & image scanning), Philo Farnsworth (1920 - 1930 USA: cameras
and transmissions), Dworkyin (1928 USA, image orthicon tube). No part of any
Baird tv device is in use in any tv system in the world today, nor was he first
...

PAL was a European joint venture. The patents were held by Telefunken AG, a
German outfit.

>Teletext, 

Yep, a BBC invention.

>Steam Engine 

Well, there was Hero of Alexandria's (Greek) aeolipile back in 500 BC...

>Telephone 

Apart from Elisha Gray (USA), and Johann Philipp Reis, who built and
demonstrated the first phone in Brunswick (Braunschweig) in 1867, a good ten
years before Alexander Graham Bell's first work.

There was supposedf to have been some tv experimenting in Brisbane in
the 1920s, but I've never been able to track it down. A sort of precursor of
BRIZ-31 perhaps?

And in New Zealand they had the 5ZB mobile radio station in a couple of railway
carriages. Thru the 1930s It would park up in towns not thought big enough to
support a commercial radio station and broadcast for afew weeks...

Was there such a thiung anywhere else?
