Cars not uncoupling at crest of the hump

[videobruce]

I received the MT magnet set (2) and discovered that the N & S poles are centered around the sides of the magnets which makes sense based on the direction the 'trip pin' is facing.
On these small silver bar magnets the poles are on the top & bottom making them semi useless unless one positions them standing up om their side which isn't practical in my situation. The cost difference in nil.

The solution was to cut one in half and extend the length which seems to solve most of the problems. It needed a longer reach past the crest which was the last problem. I still have a few exceptions which I'm dealing with the specific cars.

Are you still not following the already-proven advise provided above?  What is the point of asking for help if you won't follow it?  Why waste everyone's time, including yours?

[videobruce]

Because I didn't want to go that route when I was getting close to a working system with MT's magnets. Less hassle with placing 2 sets of magnets and far less work since the space was already cut out of the ties.
Just because it may work for others, doesn't mean it will work for everyone. I already wasted $20 on those magnets that I will never use as it is, so I did make an attempt at it.

That's twice you've thrown out the excuse that a proven concept is not proven, with your "doesn't mean it will work for everyone" nonsense.  That's akin to me dropping a tennis ball to the floor that bounces up, and you saying "just because the ball bounces for you doesn't mean it will bounce for everyone." 

Why ask for help if you aren't sincere about it?  You incurred the additional expense in MTL magnets after you were given the solution, so that's on you.

Now I am done.  You're on your own.

I've had an idea that I came up with about 15 years ago but haven't had a layout to try it on. My idea is to have a small air nozzle under/in the track pointed up hill and when the car comes to it the air is turned on and gives the car a slight push backwards and lets the couplers pull to the sides, then the air is shut off and the car rolls away going down the ramp. The air is either controlled by a pushbutton valve or done electrically by a push button and a solenoid valve.
  I got the idea after watching a guys layout with a hump yard, but he jerked the train to get the cars to uncouple over the magnets.

Neat idea - if you got it to work you could also use that same idea for retarders further down the hill.
A challenge in N-scale might be slowing the cars enough without lifting light cars off the track.

There was a hump yard in the 1970’s with air jets to keep the cars rolling and to ******** them. 
IIRC it was built by a member of the Indianapolis NTRAK club and it worked pretty well.
The air was connected to holes drilled in the 3/4” plywood base at a jig-controlled angle with plastic tubing with brass tube ferrules.  I don’t recall details of the control scheme.

I remember that layout!
The amount of air was controlled with some sort of foot pedal because I remember reading that it took a bit of playing with to get the right amount of air to flow, otherwise he said if he pushed down too hard, he could blow the cars back of the hump.

IIRC, the air was more for keeping the cars rolling into the bowl rather than retardation.   Same reason we can’t do Dutch Drops (flying switch).  Not enough momentum from mass in N.  John Allen tried a heavy flywheel geared boxcar to that end.

The Metropolitan Model Railroad Club had a working hump yard in the 1970s.  We just let the cars roll down into the classification yard at whatever speed they achieved.  The cars had to be equipped with Kadee (MTL) wheelsets and had to meet a minimum weight requirement.  I remember that the Kadee twin hoppers were an issue because they were too light without a load.  Conversely, their light weight, free-rolling ability and low center of gravity were why they were used almost exclusively in setting the longest N consists records during that era, and why they worked well with our coal dumper.

Gad, I see that Charlie got bleeped for using the proper term for automatically slowing a freight car.  The "automated stupidity" filter (as opposed to an actual artificial intelligence filter") must have mistaken that for an insulting term for a mentally diminished person. Can we get a more intelligent filter, so that we can use proper terms?

Eh? His post looks intact to me. Unless I'm in need of retardation...

Must be a profile setting?  I'll have to check mine. - Update - I don't see anything applicable.

Ah, nevermind, wrong post.

Let's see... YouTube likes to block "moron"...

Nope.

Same experience with this particular OP on another forum.

Some people aren't really looking for advice as much as they're looking for attention, it seems.
