Bringing A Heavy Train Down Mountainous Territory 

This video has opened my eyes to a lot of aspects of braking downhill. As someone coming from the Dovetail sims, I've never paid much attention to slack, and I've never played with DPU fences.

Just watched a doc about the 1989 San Bernardino incident...very scary how little things added up super quickly!

Perfect you are the first one I found do this right

Controlling a train on Seligman can be tricky when I ran a loaded grain train with mid DPU's and rear DPU's with so many rolling hills. Its hard to keep your speed under control when the grade changes so much on Seligman.

If you use that rear dup it would help you incredibly. I work the real thing on the Mountain in the Sierras and if the Dup is idled out it is working against you in the idea that it isn't helping braking and the whole wait of the cut ins or rear is against you as well. There are a lot of times you could have avoided air and kept your train under control with the rear at Brake 2 or 3 or even 4

Great job explaining everything! Where are the horn sounds from?

Great video Chris T... I love the horn. Any chance you may share in a .wav file for V3

which buttons do i apply for putting up the fence for DPU?

Found it very interesting. My training on air brakes which included Westinghouses videos of their 160 car air brake rack in action show that the internal friction of the car control valves were 1 to 1 1/2 LBS before the brakes will actually get additional air. So what happens is you take 1 pound then another pound and then maybe another thinking you are fine tuning the train. But the valves will not move with those applications. Then one of those applications the car control valves actually does reconizes the application and when you get all of those little applications coming as one giving you a lot more brake than you want. It has happened to me and basically this is what was a big factor at Lac Magatic. The power trouble caused the brake pipe to drain off at such a low rate the brakes did not apply harder, and when the locomotive brakes ran low of air and started to move the PC went off but did not have enough brake pipe air left to apply more. On steep down hills, instead of Idle I always put it in T1 or DB1, whatever you think you might need next. This if you look like you might something quickly it will cut off about 15 or 20 seconds of loading time and might bail you out. Snow or Ice, you might need the independant on for 1/2 miles before you stop at a meet or the locomotives will not hold you when you release the automatic. Or like an old hoghead told me, running at 60mph with 4 work train cars and you have to stop, what are you going to use?

I've seen a few methods about how to bring a train down hill. Is it ok to leave the brakes on the whole time down the decent? I've see other videos where you do the saw tooth method so the brakes don't heat up and melt. I'm not from the railway industry just want someone to shine the light on if this is true? Also do you use full dynamics anytime? I'm playing on tsw3

Great video! Do real train have Accelerometers? Or is it only in a sim? Thanks!

Love the vids this sim is as real as it gets.. By the way is that horn a custom horn?

How come you are not using the Duper Dynamics?

Mainly dynamic plus some air brake? I almost do such way, but I afraid of brake shoes on cars over heat, so I only apply air brake when speed is reached the track limit, when speed is 10 mph blew the limit, release the air brake..

Which sim program is this?

Can't hear you most of the time. Am I the only one?
