I'm surprised that I never before noticed this pole. It looks to me like buildings were built around it over the years and now it would be difficult to remove. Barn Bluff in the background, ADM plant in the foreground and the Mississippi River just out of frame to the left.
For Telegraph Tuesday
Close up of the old insulators on my previous photo. I had to take this before the leaves appeared otherwise I'd have lost my chance until the Autumn. Happy Telegraph Tuesday & HTMT!
A Hemingray 45 insulator hangs in the air after having broken loose from its pin and sliding down the defunct code line. This piece of glass was manufactured in 1963, which can be decoded by the numbers and dots on the skirt. This one came from mold #26, which was stamped for 1956. Each subsequent year Hemingray would simply add a dot, rather than reworking the mold. As this has seven dots, it was made seven years after 1956, or 1963.

These wires emit a constant hum that rises and falls in pitch depending on the speed of the wind. I did not find it melodic, but the blackbird seemed to feel it was contributing by maintaining a guttural croaking sound.

Glass insulators glitter in the late evening light on a beautiful fall day. Taken along the old NYC Railroad (NS Chicago Line) just east of Wawaka, Indiana.

Part of my glass insulator collection showing the variety of shapes and colors on display in five different lighted cabinets. I've been a serious glass insulator collector for nearly 50 years finding my very first insulator around 1967-68.
Glass insulators were first produced in the 1840's to support telegraph lines. Later as time went on they were used for telephone lines and power lines which included street lighting, street railways, trolleys, and interurban lines. Also used for fire and police alarm circuits and even electric fencing. Along railroads glass insulators were used for telegraph, telephone, signaling, and power use. Basically any electric line that was needed for support from insulators to prevent electrical leakage.
When there was no longer a demand for glass pin-type insulators In North America, the last of the glass insulators were produced in 1978 by the Kerr Glass Plant located in Dunkirk, Indiana.
Looks better in large.

Another look at insulators.

Powerline insulator nailed to a quaking aspen tree around 1897 once used to carry alternating current electric power from Nunns generating station on the Provo River near the mouth of Provo Canyon to the gold mines at in Mercur, Utah a distance of about 32 miles.
The Nunns Provo Station Power Plant was the first 44,000 volt hydroelectric plant in America. Built in 1897 by Luclen L. Nunn at an estimated cost of just $50,000, the plant harnessed the power of the Provo River to generate electricity and transmit power over a distance of 32 miles to mining operations in Mercur, Utah. This was almost three times the voltage of any existing line in the nation at that time, and was by far the longest.
To staff his power plants Nunn created a work study program called the Telluride Institute, headquartered near the Olmsted Power Plant, located in the Provo Canyon near Orem, Utah. Upon completion of the course the graduates were sent on to gain further education through the issuance of scholarships. Many of these students went on to study at Cornell University, where they resided at Telluride House, managed by Telluride Association, which Nunn founded.
(128/365) I noticed this impressive telegraph pole as I was taking a short cut back from a local garden centre today & thought it worthy of a photo (best viewed Large to see the insulators etc). Taken through my wound down car window for my group Telegraph Tuesday HTT! New members very welcome, we are on the cusp of 10,000 photos in the group pool today.
A Brookfield and light green HG added a decorative touch to this street. When I looked a few minutes later, they were gone. They must have fallen off when I looked away.

Another in my series of insulator photos.

In this photo, you can see the black crushed velvet that I used as a background. It has an interesting effect where you can see it.

Conrail 5935 is on the Routes 5 & 20 crossing as it makes a move during switching chores at Lima, NY on what appears to have been a warm 4/24/1979. Pinco Insulator is the industry behind the engine. Swift Chemical was the other customer in Lima and that was located behind me when I took this photo. This is ex LV trackage that once went to Hemlock, NY. By this time the tracks ended just beyond the silos in the distance.
Snow, electricity and a starling for the Telegraph Tuesday Group. Utah County, Utah.
Happy Telegraph Tuesday!
I love these things, even though I'm not quite sure what they are....
I might have to collect some....they look so nice grouped together!
A very special one: As a Pennsylvania Railroad fan it is now mine. How exciting to be standing in a corn field, taking pictures of a steam engine, running on former PRR trackage; then looking down and finding a PRR relic that cleaned up nicely even if well beaten over about 40 years with plows.
Insulator. Used to walk along the railroad tracks looking for these as a kid...for some reason they could easily be found just tossed to the side of the tracks.

An insulator display taken in my back yard of various glass insulators and hardware. One of two displays in my yard. The poles and crossarms came off the abandoned C&O Railroad in Indiana back in 2000. I planted my Red Maple tree about the same time I put the poles up, and its been taking over my display the last two years.

An insulator, with a copper wire bound to it in the manner that power lines are traditionally attached to insulators.
