The first metro to be called a subway is in Glasgow. They tried to rename it the Glasgow Underground to match London, but reverted to the old name when nobody used the new name.
In practice, throughput is not the same. There are fewer cars underground that just park on the tracks, fewer traffic accidents, demos etc. Subways make you independent of almost everything that happens above ground. When Beijing introduced the subway system, that first allowed people to estimate quite precisely when they would arrive at their destination.
Also, fewer people plan to build a park underground or use that real estate otherwise. So the above-ground use of space is restricted to the station entrances. The calculation would even be different in places like Seoul, where the subway system doubles as a public bunker system.
A subway is a metro line located underground. Throughput is the same. Its just more expensive to dig the tunnels
this is why you contract out the tunnel construction to past you, when labor was cheaper. worked in london, nyc, paris… hell of a trick
NYC, home of the $2b price tag for a km of rail.
$2b today, but if you just use 1920s labor… EH? IT’S FREE TUNNEL REAL ESTATE
A subway is the American word for metro surely? And London’s is generally called The Underground.

You seem to think of a tram. A metro is grade separated. So nothing, but the trains should be on the tracks at all times.
So this for example is a metro, but not a subway:
