Tomica World TOMY Knapford Station, Dodge + Splatter, and Oliver!!

Are these five of those double track two-way point rails? I've only got one (from the Ultimate Set), and I never thought this style of setup was even possible with physical Plarail track.
Sure, the TrackMaster station is somewhat more realistic, but it would've looked better had it been repainted to look like it does in the series. In the series, the station is very, very wide, making the Tomy version more faithful IMO, except it doesn't have the brick walls on the sides (one of which is supposed to house the Fat Controller's office), whereas the TrackMaster does.

Yes they are. Before it is pretty easy to get. Nowadays it is extremely difficult. They only comes in a package and only one per package.

Also each double crossover if I remember correctly is 15 cm in length so you need 45 cm of space just to pull off what I did plus you need more space for knapford station.
