The two voltages were separated by a "dead zone in the wire; there was a manually-thrown changeover switch under each interurban car, operated by a lever and linkage.

All on 600V.  No 1200 on the North Shore.  The TM had 1200 for a 
short time but they gave up the 1200 also.  South Shore is 1200.  No 
problem in crossing between TM, North Shore, and South Shore.  No crossings.
I don't know how the TM did the switch when they still had 1200.  I 
think they just ran slow when they ran on 600 wire.
