Good morning,
I have heard the words METRO, SUBWAY, UNDERGROUND and TUBE have the same meaning. But I'm not sure if we can make the following sentences:
1. I'm on metro.
2. I'm on subway.
3. I'm on underground.
4. I'm on tube.
Thank you.
So do you mean "I'm on the subway" mean "I'm inside the vehicle"? I mean does "subway" refer to the vehicle? Because my dictionary says it refers to the system.
Have a look at these threads on this topic:
On subway / in subway
on the subway VS in the subway
on the subway vs. in the subway

In BrE, if we say "I'm on the Tube" it means we're actually travelling inside the underground train. If we're standing on the platform waiting for the train, we would probably say "I'm at the tube station" or "I'm just waiting for the Tube".
The British system is called London Underground or The Tube. We don't use "subway" to refer to our underground rail system. It's the Metro in many continental European countries.

When I lived in Madrid, I loved the fact that the Spanish equivalent of "Mind the gap" was so long-winded! It translated to "Caution, station on a curve. On exiting, be careful not to put your foot between the train and the platform". It's only said on curved platforms - when pulling into a straight platform, they don't bother warning you about the gap that still exists.

The Glasgow Subway is a special case.
