1986, this 18 km LRT has 6.9 km underground and 2 lines, one of which is really
just a small
spur. The line was originally supposed to be a full metro but was
changed to light rail when the former CSU state's economy took a dive.
There are 4 underground stations, with a few tunnels on the line's north
end. The lines are completely separated by tall concrete walls in the
inimitable warm Stalinist style reminiscent of Martha Stewart's country
tunnels run one on top of the other, so rolling stock with one-side doors
are used. The fare is a steep 7 cents.
