That was the name of my company, guess it did involve in some ways being a teacha.

Thanks Joe, I opened Adobe Reader and then clicked on the 'click here' and it worked.

Never will understand computers!

I am sorry but the place you say to click on to get information on the #4 switch appears to not be working.

I have a Bachmann #4 switch, HO Gauge, it has the three wires connecting to the switch controller and a single black wire underneath the switch. Can you tell me what the black wire is for?

Thanks
Tom
