If you're following me on Instagram, you might have seen photos of my Trusty Red Suitcase - one of my premium travel companions. (Technically, it's probably an item, but it is a) so important and b) so large that it counts as a companion. At least I think so.)
We bought this suitcase about 6 years ago, and it has been my go-to luggage hauler for a good number of work trips by train and, occasionally, even by plane. It is large, and lightweight, and it came with four little wheels and when you gave it a push, it went "wheeeee" all through the room until it hit some wall somewhere.
That went for a while, and then somehow, it didn't go "wheeeeee" anymore. Quite to the contrary - it became rather hard to push or pull. Some closer examination quickly showed the reason: The plain bearings of the wheels had given up. They'd been made from plastic, and three of them had worn out, and the fourth had, at some place, gotten so warm through friction that it had half molten (so the wheel still hung in there, but quite lopsidedly).
Quite clearly, the makers of these wheels had not intended them to run for several kilometers through city streets and train stations, bearing a suitcase with a weight of about 30 kg (which is the maximum of what I can still handle, and which also ends up being the total weight more often than not). Probably most buyers of that kind of suitcase don't go "oh, well, I have time enough, the weather is nice, I've just spent 5 hours sitting on a train, and it's just three kilometers to the hotel, I think I'll walk." (Which is how the little suitcase has racked up the kilometers.)
So... also quite clearly, something needed to be done. Wheels made for heavy duty were bought, with proper ball bearings, and got installed by the Most Patient Husband of All Time (whose patience did get tested, as the modifications necessary were quite a few). And then, lo and behold! the suitcase went "wheeeeeeee!" again when pushed. (So much that at some point it got little stopper wedges to secure it on the train.)
But now, on the way back home from the trip to Berlin... it lost one of its wheels.
Apparently, not only the wheels in their original version were not intended to go for long rolls... there's also a limit to what the anchoring of said wheels would take. And, quite clearly now, that limit did not include hopping the suitcase up and down curbs while weighing, ah well, you know. (There's a technique to really easily get the suitcase to hop on a curb, provided that is not too high, but it's probably not the most, erm, gentle on the wheels. As you approach the curb, you give the suitcase an impulse by pulling on the handle so that the front wheels come up into the air, and then once they come down again and hit the ground on top of the curb, you do the same in reverse to lift up the back wheels. Works fabulously.)
I went back to search for the wheel that had gone AWOL, but couldn't find it again, and did not want to cut it too close with my train, so with a heavy heart, I abandoned it in Berlin Main Train station, somewhere on the way to platform 1 in the basement.
Its companion on the same side of the suitcase also wobbles a little... which means there will be some more Frankensteining of my little-not-so-little red travel companion soon. We're considering the installation of some metal plates to make it a bit more sturdy. And then I'll be looking forward to many more years strolling through train stations, and faraway cities, with it!
