    My partner Fiona has just completed all the scenarios in this sequence and has the following observations:
    There seems to be a number of bugs in the scenarios, as it says stop at a particular point, but when doing so and moving off the loco becomes derailed. She managed to get through them all after a lot of trial and error, but at the start of each scenario, you have to set everything up again in order to get started. Wouldn't it be more realistic, if the start of the next scenario started at the same point when you finished the last? ie. no need to set everything up again to get moving. Also in scenario 7, the brakes had very impact at all on slowing up the train. I appreciate that the weight of the wagons being pulled is huge, but the brakes should work. There was also an instance when resuming scenario 7, all power was lost at the start - not sure why this was the case.

    That's timetable mode your talking about dude, not scenarios. If you start the next timetable run straight from ending the last you do by staying in free roam when asked by the game itself, everything's unchanged......

    Brakes on American freight trains require proper application. You need to use both the automatic and dynamic brakes together and not exceed the speed limit on the descent. The traction limitation is most likely associated with the use of emergency braking, after which it is necessary to carry out the traction restoration procedure.

    I often see people saying the brakes aren't working - the most common cause of this is usually where brakes have been applied and released.

    First thing to remember is it takes time for the brakes to start applying - so you set them to say 80psi, it takes a little bit for all the air to come out of the Brake Pipe to bring it down to 80psi across the entire train. If you haven't catered for this, chances are you put more brake on - but that doesn't make them come on faster... so you try some more... panic sets in.

    Possibly at some point you release the brake, but on a longer train, it can take 10 minutes for that brake pipe to fully repressurise with air once you release the brakes - if during that 10 minutes you re-apply the brakes, you're not going to get tons of support from them at all. You *can* if you know whats going on - but you're going to run out of air.

    If you drop brake pipe to say 80psi, then once its all there, release the brakes - the front of the train will report 90psi quite quickly - but the back won't be at 90psi for a while. Let's say you immediately re-apply the brakes back to 80psi. The rest of the train released its brakes a while back - but as they only got charged up to say 83psi at the back by the time you re-applied, you're actually only making a 3psi application on the back of the train now - not 10psi. Worse, it's uneven and all down the train has different pressures.

    So that "same" 10psi application does significantly less for you now than the first one did. So you keep going - drop to 70psi. Ah, there you go, now you've got 20psi brake on the front and 13 on the back and it's kinda sorta behaving a bit like the 10psi you had before. All good. Now you release... quickly back to 90psi on the front, but still down at 70 on the rear.

    It'll take *longer* to re pressurise from 70 to 90... and if you hit the brakes again you're going to have to go even lower to find brakes that work.

    There's a non-forum-safe expression the engineers use that roughly translates to "wasting your air", i'll let you google it at your leisure. :)

    Bottom line:
    Make small applications to brakes, way ahead of time, give them time to take effect. if you have an End of Train Device then watch the brake pipe pressures at the rear of the train to get a clearer picture of what is going on.
    When you release, you can only release completely, there's no partial release, and if you release - you should not apply the brakes again until you've let the brake pipe fully restore (again, your gauges in the loco only tell you whats happening in the loco, and not the rest of the train, the difference can be non trivial).
    Make minimal changes to your air brakes for the above reason, and use your Dynamic brakes to manage your speed - if you find dynamics aren't coping, drop a little more air on, always be two steps ahead of the train, err on the side of giving yourself plenty of room to the limit (there are zero prizes for rushing) and then you'll stay on top of it.

    Some of the grades on Clinchfield are STEEP. The trains are OLD and not the best. The freight cars are HEAVY. Kinda worst case.

    That's why Clinchfield is one of the best routes, imho :)

    Excellent words that explain in detail to a beginner how to work with the brakes on American locomotives. But why is this given in words on a forum? Why are there guides on starting uphill in training, but there is no detailed guide in the training center on how to properly and safely take a train down a mountain on American routes? I remember my first ride on the Clinchfield route - I found myself without brakes on the descent. It's not like the European routes at all and I just didn't know how to do it right. Yeah Yes, with the help of Google I found some of your old posts on this forum about how to work with the brakes on American locomotives. And it was a great joy for me when descending from the Cajon Pass did not end in a derailment after 5 hours of unsuccessful attempts. After the first unsuccessful attempt on the Clinchfield route, I looked at American routes as something boring, impossible to pass. Gave Cajon Pass a chance, but the same thing again. Why is there no quality training? American routes are great, but they have a fairly high entry threshold due to the lack of training in basic principles. I recently started a trip at the Cajon Pass on an SD-70. My brakes wouldn't release at the end of the train. I went to the locomotive at the end of the train and checked the brake settings: the brake control was engaged. By disabling the brake control from the rear locomotives I got it all working. And the newbie probably went 10 miles an hour uphill and thought how bored he was. For me, as an experienced player, it was an interesting and cute moment that you need to check the brake settings in the whole train. But there is no full-fledged training on setting the parameters. There is basic training for a single locomotive. Yes, tutorials are boring, but sometimes you just can't do without them, otherwise the whole gaming experience will be ruined. I enjoyed the entire Cajon Pass trip. Every descent from the pass is a fascinating story. I discovered American routes as a pearl, just by learning how to ride them.Sorry for my bad English

    Don’t we still have the issue with Clinchfield that banking comms (or the old school equivalent) doesn’t work? Therefore you’re not getting dynamic brakes kicking in on any mid train or rear DPU’s.

    Have to agree with Matt though, still one of the best US freight routes in the game and it would be nice to see another similar style vintage diesel route should the bean counters authorise Matt to task his teams to build it.

    There's nowhere on training center to do this kind of training unfortunately. It's something on my mind to try and fix but don't have a path for that yet - probably need to expand the training center somehow but the way it's built is very tricky for that.

    Banking comm is still broken in the build yes - I have it fixed on my system however that system also blew up and died so I am waiting on IT to put the disks in to a machine that works and restore it all for me so that I can recover all the work I've done on Clinchfield and get going again on it!

    That was bad luck. Looking forward to it once IT can salvage the discs!

    It might not be possible to add this to a training center, but as a training module directly on the route, be it Cajon Pass or Clinchfield?
    Looking forward to the Clinchfield update!
