My Tomica World - Introductions

Are there any dates or other info anywhere on the 300 Series so we could get an idea what time it was from?

This? New in 1994 catalogue, this pic from 1995 catalogue. 未来特急のぞみ号コントロールセンタ. Future Limited Express Nozomi Control Center.
 

For the Plarail Pico device, google this: プラレール・ピコ

That's the one   

Yeah, I got my one of these because I found it in the 'junk' category of Plarail on Jauce, cost the princely sum of 70 Yen 
The only issue appears to be the box, which is rather heavily sun-faded, otherwise it appears to be in remarkably good condition, even comes with little figures that sit in the various control seats on the unit, which often seem to be missing.



True reason for buying it was actually as storage space, gonna hook it to the layout and use it as a storage yard for, fittingly enough, the bullet trains I have that don't fit on my 10-layer track tower that i've got off to one side of the layout as a storage space for my trains   I thought that 9 lanes of storage built into a 300 Series was way cooler than adding 2 or 3 more tower layers, and actually worked out cheaper as well hehe
