The guy with the yellow sleeve sure has some big shinyass work boots.

checking tracks by the look of it, but i could be completely wrong too

That is some neat engineering.

Fom what I hear, train safely in Japan is no joke. Interesting design nonetheless.

That was very cool! Definitely some interesting ingenuity...also I love kei trucks, so there’s that! :D
Around here in Nova Scotia, they mostly have converted Ford F250 and F350
s with lowerable rail wheels underneath.

That’s what I was wondering. Google’s translation
of the video
description says “This is the work of placing the rail runner used to tow the lubricator on the railroad during the lubrication of the rail joint, carried out on JR Kisaida Line.
”
“Lubricator”? Do the rails get lubricated?

If they are lubricating rail joints, it is to help them move for rail expansion/contraction due to temperature changes. The joints are designed to maintain vertical and horizontal alignment while allowing the rails to move back and forth a bit. My rule of thumb is 100/100/0.75 - a 100 degree Fahrenheit temperature change on a 100' long length of steel will cause a 3/4" change in length. If there isn’t an allowance for this change, it will cause the tracks to buckle in warm weather (we called them sun kinks - Google it, there are some awesome pics ). In the US, the mainline railroads typically use long lengths of continuously welded rail (CWR) and have some interesting techniques to deal with this problem.
Also , rails can also be lubricated on curves to ease friction and wear on the flanges. American practice is to have an automated lubricator on the track that will lube the flanges as they pass over it before a curve. Some locos also have graphite sticks that rub on the flanges or other devices to keep them lubricated as well. I don’t think that is what the crew is doing in this video, but it is another way that rails are lubricated.

T hat makes sense. Yeah I wasn’t sure if the translation was right or not. When I googled rail joint , it didn’t look like a moving part.
Those graphite st i cks sound pretty clever... I like that.

That’s common in the US too. T he kei truck setup is really clever , but the retractable wheels per might be a more elegant solution. I’m torn.

The thing is, though, I imagine the trucks with retractable wheels cost a billion times more while the Kei trucks, which are already comparatively cheap will cost far less...hell, who knows, maybe that frame / winch setup for the cart it rides on just bolts in?

Maybe. I bet that if there are “high rail” kei trucks out there, the equipment is probably a lot lighter and cheaper than what’s on those fullsize pickup s.

Yup...seems to do the job just fine too for that they are using it for in that specific case.
