Vacuum tube wiring

Question

I have a couple of old vacuum tubes that I would like to light up for my grandchildren on my train layout. I also have a Chicago Transit Authority control panel with the throttle for one of there older trains that I would also like to light up.

Where can I find wiring diagrams so I can wire them up to light? I don't want any outputs from the tubes or from the control panel so they kids won't get hurt!

Thank you,
