Vintage Tomy Takara? Anyone know what this is?

I've got a whole bunch of the original Takara trains, track and accessories from before their merger with Tomy. They are pretty well detailed, but the locomotives are quite a bit smaller (mainly shorter) with a slightly reduced wheel gauge. They will not run on Blue Tracks as they have this reduced gauge. Otherwise they look very similar to Tomy/Takara Plarail models. If you're wondering I picked up a job lot of brand new items around the early part of 2015 which is when I stumbled across this forum and the whole Tomy world lol!!

Here's an example of one of the sets I got in the job lot (the only Takara offering I could find on eBay at the moment);
