Build up your Lionel model train layout empire with the addition of the Billups Crossing Signal. Featuring flashing red signal lights, illuminated skull & crossbones, and lettering, the signal will indicate which direction the train is coming from and blare a warning sound to warn motorists of oncoming danger. Based on the 1930s sign developed by Alonzo Billups and installed at a dangerous intersection in Mississippi, the only one in existence, this accessory is a must-have for every model train fan.
