Casey, some observations and questions -Well, not me, exactly. But the line I worked in Montana - from Helena to Sandpoint and into Post Falls, Idaho.

Just thought some folks might like to see the land, if nothing else. And get some idea of how a railroader works, on the road.
Yeah, it was a bit much for a casual viewer.Casey, some observations and questions -
A while ago you posted up about how important it was that the train didnt concertina into itself by pushing too hard from behind.
As an engineer I was fascinated at how finely things had to balance within the train. You talked about miles long trains, some going uphill and some going down, causing all sorts of linear stress on the set. You talked about the train moving in opposite directions due to 180 degree bends. And watching the video, ( ok I managed about an hour of it ) I was able to see and feel the stresses you talked about.
No, the power on the head end, is all controlled by one operator. There's a "jumper cable" (what it's called in the field) run between the units - a 98-pin cable that signals to trailing locomotives, instructions on throttle, dynamic brake, warning signals, unusual status like wheel-slip alarms.So sometimes we would see perhaps eight or more locos on the front end, were they all needed for pulling ? braking ? or were they just being dead hauled to be used elsewhere ? Do all the running locos need an operator or are they managed by one driver, including ones placed part way along the train ?
With local merchant traffic, those are often set up in blocks for easy set-outs along the way. Or, they were picked up. Of course, doing work close to the head end, is much easier.Why do you sometimes put strings of heavy / full carriages behind empty carriages ? Surely a higher chance of getting the empties to stack under braking ?
Yup. In fact, if cars' brakes are bad...the rule of thumb was, no more than 5 percent of a train's cars can be bad order or cut out. If there is A car failing brake testing in a yard, it has to be set out. Failure en route, the train can continue to the next terminal where the bad-order cars must be taken out of the train.Does all the rolling stock have brakes ?
Nope. The brakes are all similar in design - yeah, that means it's basically, 1910s technology. MUCH better train brakes could be used, and are out there, for specialized applications - excursion trains, where those cars are never coupled to other cars.How do you balance the braking, do the brakes work like a trailer 'override' brake, or do they have antilock / ABS ?
That line was never double-tracked. In places there's room for service trucks to get up there.In some places it looked like the trackbed was wide enough for dual track but either it never got built or it got removed ?
Whats the story behind those occasional junctions and tunnel headers ?
No problem.Thanks for the insight into a world I really know nothing about (-:
Interesting, in its presentation. Many of those terms I've never heard; but I only knew the CSX/Conrail/CN (USA) systems. And of course, Rail Link out here.Came across this by accident. Interesting so I figured I'd post it. Hopefully @Casey Jones will read it and give us his thoughts.

Getting on the Distributed-Power locomotives. Rear set, or center set of locos
Can the door be locked once one gets inside to keep the more psycho train hoppers out?And don't be surprised if someone else tries the same. AND if that someone else is a lot tougher and more psycho than you.
And did anyone else see the news about the 17yo moron who deliberately caused a train to crash so that he could film it for his youtube channel?
Depends on the locomotive - its maker; its generation; whether the cab was rebuilt, and by whom.Can the door be locked once one gets inside to keep the more psycho train hoppers out?
Asking for a friend. Lol
I have no idea what the UP is doing.On a side note, I recently watched a UP go by with 205 cars. Had two pusher locos, one loco at about the 2/3rds point in the train, and five up front pulling. They were all running, and sounded to be working hard as they went by. Longest train I'd seen in awhile. Usually they are in the 100-150 range, or short locals.
Maybe, but they all sounded like they were pulling hard as they each passed by. Me and a friend were only about 30 feet from it, so we could hear it pretty good. It was going over a bridge, and we were under it and a little off to the side.Our rule of thumb was, no more than four locomotives on the head end, online. More could be dead-in-tow,
Depends on the locomotives. A 2500-hp GP-20 (early 1960s; a few are still out there) is not even comparable to a 6000-hp GE AC6000CW. Both raw power and final drive (DC versus AC traction motors) are wildly different.I'd heard that five locos can pull more cars than the couplers can sustain, and that if a train has five locos in front, it'll always have pushers and/or distributed power.
Although this was on double track, there was no on-coming train.Oncoming train on another track.
It was moving. At least 20mph, but not much, if any, faster.Or to show that the train was stationary
There are no crossings anywhere along where I saw this train with a dimmed headlight. He turned it to bright just before he passed me, but I was grade separated, so I doubt I was the reason. He wouldn't even been able to see me, where I was at in relation to the train and tracks.Those headlights and ditch lights are so bright, on full-intensity, you can't see anything around it. Like, say, a road crossing five car-lengths back
Nope. This is all grade separated, no parallel roads. Nearest level crossing was a mile behind the train at the point I could first see it. Tracks are up on a bridge. I was on the grade under, but to the side of the bridge watching it approach and pass by. There are no roads there. Just a river and a big wide flood plain with no roads or structres on it.He may even have turned it off out of courtesy for road traffic, if it were night, the track paralleling the road, and no
Yea, could be that. Headlight went bright about halfway across the bridge.Or, it could be, his unit's headlight control is mistakenly set to TRAIL.
