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:

Bricks with holes

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.

This is the part: http://www.bricklink.com/catalogItem.asp?P=7049b And these (for example) were the wheels: http://www.bricklink.com/catalogItem.asp?P=wheel2a

    Makes sense as there was also wheels and tracks in the haul. Thanks a lot.

    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.
