2021Aug20 — I am TOP RATED on this marketplace with a current 12-month FEEDBACK rating of 100%, and I offer Combined Shipping. See my last 2 pics for my eBay Seller Level and eBay Feedback.
For shipping I have specified a handling time of 10 business days.
I have for sale an American Flyer model 759 crossing signal with bell which I have enhanced for separate (independent) light bulbs operation. Red light bulbs are included, your choice of 18v painted red or 18v clear red, one of each shown in pics and video. (I prefer the painted red.) There aren’t any cracks in the bell of this item, as is often the case, and the bell rings nicely.
Also included is a short length of rubber hose to ease any future bulb replacement, which otherwise doesn’t seem to be humanly possible if a bulb is tightly installed.
The enhancement consisted of …
o Converted a non-insulated Fahnestock clip to insulated.
o Added a new non-insulated screw terminal to the base.
o Cut a slit in the metal strip connecting the two light bulb sockets.
o Drilled a 1/16″ hole in the stanchion.
o Threaded a 32gauge wire down through the stanchion.
o Soldered said wire onto the short part of the now-cut metal strip.
o Connected said wire to the newly insulated
Fahnestock clip
.
o Added some spots of solder to the riveted electrical connections. AF riveted electrical connections are notoriously weak and frustrating.
o Painted flat black the lights crossbar where the spots of solder were added.
o Reworked the chimney mounting on the shed. The original chimney was just stuck into a hole on the sheet metal roof and was flimsy and loose. The present chimney is from a caboose.
Nothing you couldn’t do yourself if you have the parts for the new screw terminals, the necessary tools and the skills to use, some 32gauge wire, and the patience to thread said wire. Or, much easier, you could just buy this one.
Check out the video of this enhanced crossing signal with bell in operation at 18v, per link below. With a flasher circuit the crossing signal presents a much more attractive and realistic operation compared to the usual method of using wheel track trips to erratically flash both light bulbs and ring the bell.

The flasher circuit shown in the video is my custom design, definitely not a part of this deal. It consists of a latching relay (12vdc), a flasher circuit PCB (12vdc) from China, and 2 buffer relays (12vdc) to switch 18vac for the crossing signal bulbs. Any kind of track trip can be used to latch the relay well before the crossing, and likewise another track trip of any kind can be used to unlatch the relay well after the crossing.
Minor issues …
o There are small chips in the paint on the green base and white crossbuck front. They could be touched up but I don’t have paint to closely match. I’ll leave that up to you.
o Viewed from the top the crossbuck and light crossbar don’t quite sit square with the base. I tried to slightly rotate the stanchion but it’s tightly swaged into the base. Probably best here to leave well enough alone.
I’ve adjusted the bell for good ringing up to 18v. Too high a voltage will make the bell buzz instead of ring. Adjustment is made by slightly bending the bell mounting bracket in or out. I will ship this item with the shed little mounting tabs not bent over in case you need to make an adjustment. Those little metal tabs can take only so many bendings before breaking off. BTW, twisting the tabs works better than bending the tabs.
