Reply to "Operating switch tower...direct power/multiple tracks?"

Thanks for the replies so far!  I'm using the MPC 6-2324 tower, so it's still "old school."  I'm using a ZW on one line, a KW on the other (still old school.)  I've got the tower lights rigged to a separate transformer, so I can turn it on/off with my other lights.  I'm using an insulated track section on the line farthest from the tower, but with modern locomotives, I've really got to crank the power to get the solenoid to trigger, thus my dilemma.  I'm also concerned about running the power to the tower off two different lines...will that cause a problem, especially when two trains are triggering the tower at the same time?  Thanks again, and hope this gives more info!
