Grey Track

Hi guys,
I thought I'd just make a thread that can document all the sets that come with grey track, just so if people want to make their layouts out of grey track instead of blue track (like myself) they can.

First one is the R-26 and R-27 viaduct rail packs (curve and straight)

The second one is the Overpass Way Shinkansen Rail Set which comes with 3 straight rail, 1 stop rail, 4 curved rail and 8 double radius curves.

You can also purchase J-24 Rail Yard which comes with 2 straight rail pieces

There is also a Tomica World sets that come with grey rail. The First one is the IRC Train Set which includes 7 straight rail, 14 curve rail, 4 Slope A rails, 1 straight slope rail and 2 switch rails

There are definitely more sets, Particularly Plarail sets but these are the only ones I know of. If anyone could include more that would be greatly appreciated.
