I guess additional order of LRV means MUNI's extension plan is going well.
What's that?
MUNI, the transportation operator in San Francisco, foresees inauguration of Central Subway in the near future. The Subway branches from the conventional 4th and king station to Chinatown.
So, more rolling stocks will be needed.
