Quoted from Miguel351:That's really cool, Coyote. Very interesting stuff!
Here are a few questions for ya:
What were you first: an engineer or an electrician? How did the one lead to the other? Or did it?
Do you do the signal maintenance for the small railroad company or for the local county or state?
How far back on the tracks are those sensors placed? Are they placed at that spot based on average speed of the train for that area? Or what other factors?
What kind of engine do you drive? In other words, when you say it's a small excursion railroad, is it a place like this: Roaring Camp Railroad ?
Any railroad-related pet peeves?
I actually started out as a computer programmer. I still am, actually. (That's my full-time job.) When going to college, a local short-line needed weekend help and I applied and got hired as a freight conductor. (Hooking up trains, working with the engineer, dropping off loads, picking up empties..) One of the only reasons I stuck with it at the beginning was that it was a fantastic stress relief - getting to knuckle (bang) together 40k-ton freight cars, at even 5 mph, made a huge noise, and was fantastic for letting out some stress.
For all but a few very few exceptions, railroads handle their own maintenance. (They may contract out, but it's under charge of the railroad.) State, county, etc don't do maintenance. So, the crossings I maintain I do for my current railroad, and am on-call for emergency work at another.
The 'sensors' vary. There are several different types of train detection, none(*) of them use real 'sensors'. They use the rails as a 'circuit' - current is sent down one rail, and then picked back up by the other when a train 'shorts out' the rails, in short. Some more advanced systems watch inductance change between the rails, and can not only tell where the train is, but which direction it's going, and how fast - and time it so that the crossing activates with the right amount of time before the train arrives.
(*) - There are some very new train detection methods starting to become more widely used in the US, but have been used over the world for some time, commonly called 'Axle Counters'. In this case, there *are* inductance sensors (much like those squares/circles found in the pavement at a traffic intersection), and these little sensors count the direction and number of axles. In my pictures above, that crossing is the first public crossing to use this detection system in Maryland. In this case, the sensors are placed about 440' feet out, for train speed of 10mph, and warning time of about 25 seconds.
When I engineer (not to often, because crossings take up a lot of my time), I operate a GE 44 ton. (Similar to: http://www.trainspotted.com/photos/3840dcaed53860047ad7ba7a17cd65b0/Port-Stanley-Terminal-Rail-Winnie-diesel-locomotive-44-ton.jpg .. But ours doesn't look nearly as pretty..Heh.) By 'little', I meant that we only have about 8 miles of track, and don't haul freight - yet. (We're looking at a few freight customers..) It's an excursion railroad, which is a 'step down' from working freight back when I was in school - however, after moving and having to give up my old railroad job, I needed to stay in the industry - I liked it too much, and with computers and electronics in my background, signals and train control always drew me.
Pet Peeves? Huh. I'd have to think of that one, actually.. Nothing really comes to mind. EXCEPT maybe coworker that like to chat on the radio far, far, FAR too much.
Quoted from Richthofen:How is the railroad industry holding up? I know the industry got a boost due to the oil trains as the US is producing more domestic petroleum, but I'd love to know whether you think the industry is on the upswing or downswing. I've always thought that the US would benefit from more rail investment.
Are pinball machines ever moved by rail? Dunno what is moved by intermodal transportation these days... but I always thought it was crazy that so much goes by truck when we have passenger and freight trains crisscrossing the USA every day.
Right now, the industry is pretty level. Last I checked, 2016 was slightly down on # of carloads transferred over 2015, and I think I heard a report just earlier that Jan 2017 was up maybe 3%. So, I think the fall of coal hurt a lot of the smaller railroads out here in the east (like in WV, and central PA) but the oil is booming the midwest guys. (Though, I'm not sure how the new pipelones will affect that..!) Also, at least up until our current President, there was new rail loading facilities down in Mexico that was allowing more good to be imported/exported. Don't know how the current administration will change that. Excursion railroads - like my current one - are doing really well, for the most part.
The only way pins would be shipped by rail would be if shippers (Stern, JJP, etc) didn't use LTL, and had whole trucks. Then they would use intermodal containers and send 25 out west, for example. (It's *possible* some LTL carriers have their trailers shipped by rail, but the likelihood of that would be a lot less..) Intermodal is just about anything - as long as it's a full container. USUALLY, it's shipments coming from ports - i.e. Boats from China. (China loads one container, destined for Chicago. It arrives on the west coast, is offloaded form the boat on to a train, train takes it to Chicago where it's unloaded an put onto a truck to get to Walmart's warehouse. Autos, Intermodal, and oil trains are biggest consists right now, in North America.. Grain is close, in the start of the harvest season.
