Bought my son a 1970's Tyco, HO scale, F9 for his birthday. I want to replace the burned out bulb for Christmas to go with his new track. Can't find any markings on it and don't want to get the wrong voltage. I am new to all of this and have no clue. I don't want to set his engine on fire on Christmas Day! Any help would be appreciated.

Welcome to the forum. Generally, any 12 volt rated bulb will work OK. If you were to go to a hobby shop they may be displayed as 14 to 16 volt. In this case it doesn't matter if it is labeled for DC or AC. Either will work well. Frequently they will be packaged as "grain of wheat" bulbs. There are also "grain of rice" bulbs which are smaller.
A toy train transformer puts out between 0 and around 16 volts depending on where the throttle is adjusted. Rarely will you want to operate the train at full throttle but the bulb should be capable of handling this peak voltage. In normal operation, you will be running between 8 and 14 volts.
Hope this helps, Randy
Randy

LifeLike makes a bulb that should be a drop in fit. You pull the wire off the old bulb, solder it on to the new bulb, and then pop the bulb back into the metal clip in the engine.

Many Radio Shacks still carry a selection of small bulbs. The Tyco bulb has screw-in threads on the F9 I just repaired, but just slip in a clip. 12-14 bolt bulbs are all you need, preferably the 14's, which Radio Shack carries back in those grey drawers at the back of the store in the hobbiest area. Just take the bulb in and match the diameter of the base to any 12 to 14v bulb they carry. I assume your F9 has a clip in the front to hold the bulb. Grain of wheat are usually too tiny to give much light for these engines.
