What are these bricks with filled interior and holes/tubes going through?

Question

I recently bought at haul and found a bunch of these regular sized bricks. Can anyone identify the for me?

They are 2x4 bricks, but with holes in the side of the bricks:

It says Lego on the stud, but no part numbers are to be found anywhere, so I guess they are old.

Any help is appreciated.

They were used until 1990 for trains, the holes are there to stick in the wheels.

You're welcome. @Stephane, no I mean the 1990's, it was still in basic building sets in the late 1980's and the early 1990's.

@Mr.ShinyandNew安宇 you're absolutely right, that's why I wrote "until"! The white ones though, the ones in the picture, are actually only from the 1960s amd 1970s, you're right.
