LOL...my over the hill brain assumed that R-17 referred to a train and I was looking all over for one. 🤔
Those red viaducts are actually a remake of the hard to obtain vintage bridges from the past. They are remade a little taller to fit the height of the modern risers and made so that they are self contained meaning they don't need a riser/pillar on each end to hold up the rails. I would be very interested in getting some of these if they had come in the grey color 😁. A coupe of years ago I worked with Nigels to recreate these with his 3D printers in grey with the same modifications that they used in this new release. He did a great job.
Thanks for setting me straight Dr Chris 👍
So I now assume that Plarail is no longer making these three way points that were only released in 2014. I still don't understand a reasoning or logic as to why Plarail/Tomy re-uses these numbers on new releases.
