In San Francisco, I found a strange rollsign of a MUNI train in Balboa Park, San Francisco.
The rollsign displayed 'China Town', despite the fact that no station called 'China Town' is on MUNI Line and that no MUNI Line passes through China Town.
In conclusion, I knew that it was a rollsign which is prepared for Central Subway.
Central Subway is scheduled to run from 4th and King(Caltrain) to China town via Union Square by 2019.
The picture of the rollsign 'China Town' is shown on the following website.(Not this diary)
