Delaware-Lackawanna PO-74 branches off the main to drill the Trevdan Building Supply and Arden Mills facilities in Pocono Summit, PA. On this gloomy Novermber day, a trio of Alcos would be the stars of this chase. Trackside are remnants of old telegraph poles that traverse the right of ways of many old railroads far and near. Variously shaped and colored glass and rubber insulators still litter the poles and grounds for miles around.
Whitley County, Indiana April 1973
Insulator hunting along the main Pennsy Line (Penn Central at the time) near Coesse, Indiana in April of 1973. This line had by far the most variety of insulators that I got for my collection, at about 135 different insulators. CREB and Petticoat beehives style of insulators were a dime a dozen along this line. When I first started hunting this line in 72 there were six crossarms, for some reason in 73 they took down the bottom crossarm along the whole line.
Noticed that some of the insulators are without wires. Even as early as 1973 most communication lines were becoming obsolete for railroad use. Telegraph lines were done except for maybe a Western Union line, and there might be a few telephone lines still in use. The signaling circuits would stay up until it became dark territory after Amtrak left in the early 90's and the signals were taken out. The pole line was taken down in 1997.
Lucky for me, I was the very first person to completely walk from Fort Wayne to Warsaw, Indiana right after they took the pole line down. Since they left the poles on the ground, I was able to grab the better and most of the older insulators. Many trips were made.

This 34.5 kV pole was shot on 9/3/2024. Two days later, almost all of these 1960s era insulators were shoved into a Hyundai and carted home. The few remaining were carted home the next day. I’ll hang them from some trees with bird feeders at the bottom. They work well to keep squirrels away. I guess they find it difficult to climb down a chain of these.

for www.flickr.com/photos/emilyduffin/2938393741/ -- the pole with insulators I saw right before I came across this pole several yards up the tracks. Wires are still hanging off those insulators.

Fifty two amber Whitall Tatum 216s and some other various glass and mud, and one bullet damaged plastic recovered on a quick hunt, sit on my friend’s 2005 Buick granny cruiser.
Good times!

Here is a set of Missouri Pacific insulators mainly found in the 1990s when Union Pacific was removing code lines from several different subdivisions throughout Missouri and Illinois.
The white style on the left was used on the lower voltage power circuit located at the end of a lower arm. The second and fourth ones here, were used on the signal code circuits. They were made by different manufacturers. The cable tie insulators third in line was used on the top arm on some lines, where the 600 volt power ran. Not all MP lines had the 600 on top construction.
The first, third, and fourth insulators were made by General Porcelain Co, and the brown ones could be found sporting G.P.Co. rather than MP. I always hoped to find one marked with both, but never did. MP markings varied from being on top, on the side of the dome, and on the skirt, sometimes upside down. The markings on the 600 volt insulator were often very weak to unrecognizable, making finding them difficult despite the insulator itself not hard to find.

Given the age of the Goffs Schoolhouse Museum and the artifacts as well as the isolation of this rural area, some of these insulators were used for electricity rather than communications. This collection was on the periphery of the Outdoor Mining Museum. The Goffs Schoolhouse Museum was established by Dennis Casebier while he was researching the Old Mojave Road which was the far western end of the Old Spanish Trail. The Old Mojave Rd. began on the banks of the Colorado River and proceeded west to Los Angeles.
