  1. That is pretty fascinating. I find it interesting that those pins look pretty much the same wherever I’ve seen railway lines – must be a good design, I guess!

    I was thinking that AS 47 might be a really early australian standard number, but I think (after a little searching) that it’s referring to the pin being suitable for either 47 or 50 Kg/metre track. That company (Pandrol) still make railway fasteners, by the way (you can tell I’m having an interesting day today when I spend 5 minutes or so looking up railway fasteners on the internet ;)).

  2. Those reverse-torx coach screws are unusual too, I haven’t seen them before….okay, I’m going to stop now ;)
