[abdullahseba]

on the London under ground train at the museum I work at http://www.walthamstowpumphousemuseum.org.uk/filming.html there is a metal bit sticking out of the train that says Sinclair on it. is it same Sinclair that made the Sinclair c5

so what actually is it ? looks like a handle to me. Don't forget that sinclair went by the by quite a few years ago. chances someone is using the name. it happes often. Like Quad still exist in name but it's just a front badge for some taiwanese made gear made by a company that just buys up companies and uses their original names.

It's an antenna made by Sinclair Technology (probably)

Is that the same sinclair who made the C5?

[Simon]

I doubt it, they are a division of someone else so either a coincidence or someone who bought the name when sinclair went bust.

the train is 1967 & I think its a kind of electric contact

It's a "Heavy Duty 380-400 MHz Train Antenna" . Part of some form of safety communications system (rather than telemetry).

As I know trains does use fiber optics or twisted pair over TCN [http://en.wikipedia.org/wiki/Train_Communication_Network ].

Trains could not use wireless in it's sensor network, even for a backup system.
Sir , what telemetry exactly that you refer there?
