  1. Train braking is terrain and condition Dependant, a decent rule of thumb is a 100car train on level track takes 1 mile from 50mph, if its down hill or wet or cold double the distance. The changes don't end there, most mixed consist trains average half loads half empties, coal, grain and tank trains are most always all loaded or all empty so again double the stopping distance. If there was a curve or building back up the track restricting vision of the truck the brakes may not have been activated till a couple hundred feet before the truck.

  2. The AD-IP is a good dryer, but its just as cheap to buy a new one as to rebuild it with a cartridge and purge valve kit. As for the heater like above if its a part time use antique truck and you keep the water out of the system and dont use it much below freezing its no big deal, also the heater is really only needed for about 20-30 minutes after startup. Once the engine and compressor are at operating temp the air going thru the dryer is over 100degrees therefore hot enough to not freeze up. I actually dont have one on the superliner, I have an AD9 in the garage for it but I use it so little it just hasnt bothered me yet, I still drain my air tanks every time I drive it and do with trucks with air dryers also so its not a big deal for me.

  3. AD-9 is a bulletproof dryer, the rebuild is straight forward and consist of some o-rings, a spring and the actual purge valve center section, comes apart and back together in about 20 minutes. the dessicant cartridge can be a pain to get broke loose, I use a big filter wrench or chain wrench but once broken loose it screws right off and back on. Itll be about $40 for the rebuild and $60 for the cartridge, never do just one do both at the same time once a year or every 100,000 miles.

  4. Chains, with two crossed over the front edges of the mats if it were me, coincidentally I have a friend that is working a deal to start building those and im in the loop for the haul within 500mi or the rail load out.

    paul, I never could get the hang of ropes, just couldnt keep em tight for some reason, and I keep a couple lever binders on the trailer but much prefer the ratchet type. I think lever type binders work ok on anything with some give like rubber tires but anything solid or on tracks i go all ratchet binders.

  5. The late 80's early 90's were weird times with Mack, seems you could order trucks with the same spec 3 months apart and get something different at delivery. I'm sure Mack would say it was constant improvement to their product but it makes parts hunting annoying. I've seen lots of 8 lug trucks, most were bulk haul trucks around here, fuel tankers, bulk tankers, freight trucks,etc. Seems they were touted for more strength, quicker changes and lighter weight but never caught on market wide.

  6. Today's RR crossings have computer circuits that will judge the speed of a train . Just throwing a pipe across the rails won't gt crossing gates to lower or a signal to drop to red. You would have to find the isolated sections of rail and short them all to fool the signal system computer into thinking a tran had passed. Todays signal systems are complex and they are built to avoid faulty signals and train location reporting....laying a pipe across May have worked 30 years ago but not in today's world.

    Hate to break it to ya but they arent all new, we (CSX) just replaced part (not all) of the original signal system from the 1940's and 50's from the Chattanooga Subdivision. It would never have been replaced but it wouldnt work with govt mandated PTC so one section at a time its getting swapped out, but its still just a track shunt to start the grade crossing system , its more intuitive but you can still fool it with wire and a resistor.

  7. I was wondering when this was going to get posted. At first I thought HOLY SHIT thats my old trailer. Upon further review not my old equipment. Taylor Trucklines in Mn. they just got into HH from what I heard. Think there hh days are over

    was wondering if this was why you sold the truck,lol

  8. Always, always, check the unloader side of the system first for this issue, if its not an unloader line leak its the unloader seals 95% of the time. Changing governors wont fix a recurring dryer purge, changing compressors only fixes the issue if the unloader seals are bad and its a whole lot cheaper and easier to replace the seals than the whole compressor. I think Ive fixed this same issue a hundred times maybe more, its a very common problem, I used to keep a squirt bottle with soapy water and an unloader rebuild kit on my toolbox when I worked at Howard Baer it was so common. Glad you got it fixed before you spent big money on a compressor.
