Yeah, that's suspiciously absent from my video. I'm uploading another one now:

or

(The Google version is really jerky I'm afraid.) This one starts with the train
being loaded, but then follows the train to the next unloading module so you can
see that. Next time, I'll try to get a video of the train itself at all the
loading and unlaoding modules - there were four (two loaders, and two
unloaders), all different, although both unloaders used a dumping mechanism that
Steve Hassenplug came up with and I shamelessly copied... because it works far
better than anything I had at the time.

Because of the standard throughput requirement (that each module must handle at
least 1 ball per second, or "bps"), a module *can't* be overwhelmed, as long as
the first module in a line never releases balls at more than 1 bps or so. The
only "overwhelmed" modules were ones that for some reason jammed or slowed down
below that standard. To make sure that 1 bps rate is properly established, the
train unloading stations either incorperate or are immediately followed by
"clocker" modules - modules with a variable delivery rate to keep the throughput
at or below 1 bps, and smooth out the otherwise episodic flow from the train
unloading stations.

| (...) It was quite an impressive array of modules. I wonder where the trains got emptied, and if there ever was an overflow in some module, given the enormous number of balls? Cheers Jürgen (18 years ago, 5-Sep-06, to lugnet.robotics)
