6-24112 Lionel Oil Field with Bubble Tubes

I have one that works great on 15 volts with 14 volt bulbs. (Have to heat the tubes!) Not sure what you mean by in line. Each bulb should be in parallel. Has someone re wired this?

I think the power supply is underpowered. There are 8 incandescent bulbs that you are trying to light.

Return the wiring to factory state and use a larger AC power supply.

Carl may have it. That is a 20 watt supply. Look at the bulbs, they should have information on the brass so you can figure the load. Is anything else connected?

Very rare meercat version.

Thanks fellas.

Use a separate lionel 180 power house, with a power lock on house. This should solve your problem, you should try to have all your accessories on seperate transformers. I have so many accessories and two tracks on my layout, I have a 180 on 1 track

A 180 on 2nd track

Another 4-180s between all my accessories

It took time to figure out why I was having problems at first, just under powered.

I have spent hours on perfect clean wiring, always use good quality wire 18 gauge too

Good luck, take your time, have fun with it, remember hobbies are more tinkering than up and running perfectly.
