LEGO train tracks have 3 holes in each of the segments:

Train Tracks

I understand the two outer holes are used with a throw-away piece to keep them stacked while shipping, but what is the center hole for? Is it just for saving a bit of plastic? Or perhaps just a planned 'shipping' feature that was never used?

    Throw-away piece? Throw-away piece? You don't throw away LEGO parts!!! – Joubarc Dec 17 '13 at 05:19

    Indeed, you keep those pieces to keep your rail bits in line in storage. – gev Dec 17 '13 at 07:06

    I bet you keep the bit in the middle of the coin sprue too :) . Seriously though, use a longer metal piece to hold more tracks together. The plastic holder is just a waste of space, and seeing as it's crimped on the end it looks bitten. No bite marks in my collection thank you. – Josh B Dec 17 '13 at 21:49
  • I'm just saying, I used on of these in a MOC once. – Joubarc Jan 23 '14 at 15:04

The larger hole is present in older 9V track as well:

9v curved track

I've never actually done this, but I've always assumed that the hole is there so that the track can be screwed or nailed down if desired to create a semi-permanent layout. This is common practice with traditional model railroad track:

  • I'm fairly confident that's the reason. There was a hole in 12v gray sleepers as well, by the way. – Joubarc Dec 17 '13 at 05:19
  • I suppose it makes sense with the curved rail pieces since they don't clutch directly on to a baseplate in the way straight pieces do. It – Ambo100 Dec 17 '13 at 10:33

    Given that even a large track layout doesn't weigh much, and the train itself does, the track can slip around quite a bit as the train goes around corners, unless the track is secured to the surface or weighted down with attachments. I am fairly sure that this is what that hole is for. It's even tapered, to fit a screw head or nail head flush. – Mr. Shiny and New 安宇 Dec 17 '13 at 14:08

    Yeah, the countersunk nature of the hole makes me pretty certain this is for screws/nails. Not sure why I didn't think of it earlier :) – Josh B Dec 17 '13 at 21:50
  • The countersinking does as said give the likely reason. Interestingly (or not) I noted a picture of a piece of track via LDdaw in another question and you could just about make out the fact the central hole on that generated image was countersunk too. – AndyF Jan 08 '20 at 23:35
  • @Mr.ShinyandNew安宇 try making a circle and running even a single citytrain on full speed - if your floor/table is smooth enough, the train will just spin mostly in place with the track flying around, it's quite funny to watch but definitely not the point :) – htmlcoderexe Mar 23 '20 at 12:03
