For those wondering...

For those wondering... here's the picture as posted on the Kato USA web site.

According to their info, 33mm spacing between tracks, and 248mm (62x4) long. Standard T-Trak module length is 310mm (62x5), so that leaves you 62mm for something else like a power feeder piece. I'm seeing a lot of potential for things like single crossover modules on either side of junction/interchange modules to allow both tracks to access yards or other diverging tracks.

Don't like the look of the resin ties though. I've already settled on concrete ties as much as possible for my modules, even cutting double track pieces the length of the track to get the single track pieces I need opposite turnouts... but I've been keeping the wooden ties on turnouts. I REALLY don't want to have to paint either the resin or wooden ties to match one or the other. I've got enough painting to paint wooden ties to match concrete already! Still going to have to do a little painting on this one... the last half-tie is resin, not concrete... that's going to look silly connected to concrete track!

Prototype

FYI- Here in Florida, the FEC RR their turnouts are with wood ties and their main line have concrete ties and the combination looks just like your track.

Weird

Those ties look like what a model railroader thinks should be on a crossover. I have never seen one with those huge ties. They would be about 25' long and I doubt any railroad would waste its money on that.

Unless of course that is how it is one in Japan!

Nick is right, wooden ties under turnouts in concrete track is very prototypical. It save making a separate mold for all the different lengths required on a turnout.

Those aren't wood ties,

Those aren't wood ties, according to Kato... they're resin... plastic. That can explain their length - in RL they're probably extruded and cut off to the necessary length.

Their wooden ties are almost black.
