Himalayan railway tour puzzle.

« on: December 07, 2022, 12:27:44 »

One of my friends and his good lady are exploring in India right now, traveling around by railway.....lucky so-and-so.
He sent me the attached photo shortly before departure on a Himalayan leg of the trip wondering what the wording "ball and sausages packing" on the end of the carriage meant.
Although not a member himself, he wondered if anyone on this forum could shed some light on the matter, hence this post from myself.
Any suggestions would be welcome and I can forward the replies on to him.....or tell him to log on as a guest, off course.

1.Suggest he joins - it's no cost, straightforward, he has nothing to loose and much to gain from it being easier to navigate the site.

2. From Wikipedia, looking at ways to pack spheres (balls)

Quote

Sausage packing
An arrangement in which the midpoint of all the spheres lie on a single straight line is called a sausage packing, as the convex hull has a sausage-like shape. An approximate example in real life is the packing of tennis balls in a tube, though the ends must be rounded for the tube to coincide with the actual convex hull.

Of course, Sausage packing differs from Pizza packing ...

Likely to be something to do with the type of wheel bearings that this coach rolls on, I suspect. Other than that, the mind boggles
