    My maternal grandfather worked for C&NW as a gate operator prior to the automatic crossing grade gate systems. I remember the "hut" on stilts he had in a northwest suburb of Chicago, as I got to spend a night in it with him - he gated the last train into Chicago and had to stay there overnight! Huge (to me at that time) control board for two intersections having a two-track mainline. Labor-intensive, and of course subject to the gate operator falling asleep! Good times back in the 1950s.

    I managed at a place that rented cranes. One day some guy at the railroad called me inquiring about renting a crane to remove two old crossing signals so they could be replaced with the larger crossing signal lamps. I had always wanted a railroad crossing signal so I struck up a deal with him. He stopped by my workplace and he told me that he would give me the crossing signal but I was going to have to take some other stuff. It was inventory time and the railroad head honchos wanted a bunch of old stuff gone so it wouldn't count on the upcoming inventory. Long story short I wound up getting three full tractor trailer loads of lights, crossings, cabinets, signs, cantilevers, cast iron crossing signs, old glass relays and about a hundred other things that I can't even remember. Over the last thirty years I have given away about 99% of the stuff.

    My grandfather was a gate operator in Arlington Heights, IL for many years before automatic grade crossing signals were installed. He had an elevated "hut" on stilts, and a coal stove to heat it as he stayed overnight. As a young lad I'd walk the tracks scrounging coal with him as my "job" for getting to stay in the hut overnight, riding the train back to the city the next day. What memories those times made! One thing common to EVERY "advancement" made in this video was the elimination of humans, much for safety and reliability, but also for economic reasons; we lamented the passing of the caboose for the same reason as it was the end of an era.

    People tend to forget that almost all of the class 1 railroads were built fifty years before the first mass-produced automobiles and trucks. It used to be that if you were moving to a new city, your furniture would be put on a rail car, and transported to and from the terminal using a wagon pulled by horses.

    I worked for CSX 37 years as a communication tech. Technology changes about every 5 years. The railroad is full of technology. Doesn't look like it from a distance but it is. Upgrade on his hump yard info in the video; Car goes over the hump, radar gun records the speed so it can get the retarder to slow it down if needed, Car id tag on the front is read by an AEI system which will tell the computer which switches to throw and send it down the right track so it will be heading towards its destination. Electronic sorting system. AEI tag readers provide listing of cars in a train. Satellite links to wayside radios and signal switching bungalows for instant control. They need FCC licensed techs all the time.

    I worked in the billing department and those AEI equipment id tags were very useful when it came to tracking movement of products and entering the correct car numbers onto the waybill. Especially when it came to coal trains, grain trains, intermodal flatcars and any other manifests. Sometimes the AEI readers would skip a car number, and it took just a little research to determine what the missing car number was.

    Wow, to see semaphore signals stateside in action, a rarity. The ball on a rope was common here in the UK, replaced with a flat disc and bar until semaphore became more commonplace on British and other countries networks. My late father began his British Rail career at a signalbox called North Kent Jnc which was historically the very first signalled railway section in the world, he went full circle to finish his career at London Bridge power box but returned to lever boxes in retirement at Swanage Railway. Def pleased to see them US semaphores, like the idea of the third position of the arms which I guess is horizontal=stop, 45 degrees=caution and straight up=full clear ahead? Ours were only ever two position and some of the old gantries like Rugby, Newcastle, even Bath Green Park were incredibly complex rod and cable setups that required massive signalboxes and large teams of signallers.

    I used to work as a technician for Canadian National Telecommunications, which was part of the railway. Back in the mid 70s, I worked in Northern Ontario on the systems that worked along the tracks. These were the old open wire carrier systems, that carried multiple voice circuits over a pair of wires. Some of the traffic was for signals and also for the dispatcher's phone, train to wayside radio and more. I also worked on the teletype machines and circuits that carried the railroad communications. In addition, I worked on a system that managed freight train consists. My work would also occasionally take me into the dispatchers office, where I could see the big board, showing operation of rail traffic in the region. I also frequently rode freights, to get to work locations. In addition, I managed to salvage a Morse sounder from the CN office in Geraldton, Ontario, before it was demolished. I still have it here.

    After the introduction of narrow band by the FCC, communications between the section trucks, track inspectors, signal maintainers, trains, etc have gotten worse, we used to communicate and hear everybody clearly on wide band VHF from one end to the other end of a 2+ mile tunnel, now days we sometimes have to have the DS help relay our communications between the sections, track inspectors, and maintainers.

    In US it is far different than Europe. Not sure if it is in your locos too, but we have some systems that really iimproves safety called RADIOSTOP. Alarm signal to radio triggers emergency breaking. It is not often in use, but when something goes wrong and two trains get on same track (control devices failure, human error or any other accident) it saves lives by stopping both. All railways should be still modernised, especialy contol and safety devices.

    Cool vid, I recall seeing a crossing bar manually cranked when I was a kid, mid 60s, can't recall where exactly but it was in south NJ.

    My mom used to work in the office at Seaboard Railroad (Richmond, VA) on Broad Street right off of I-195. When they moved to Florida, she chose not to go. A co-worker/friend of hers went though. This was back in the early 1960s and the Cuban Missile Crisis. Way before my time (1971)

    Thats the phase motion detector. In short it turns the track into a tuned circuit when the train rolls onto the section it alters the tuning and activates the crossing. While its moving the tuning is constantly changing holding the crossing active. If the tuning isnt changing but not its normal after a preset time it times out and deactivates the crossing but the instant it changes again it reactivates IE a train has parked in the detection zone.

    You missed one of the coolest signals around. The railroad torpedoes!! They were still in use in the early 90s, might still be.
