loco storage

I seem to recall an old MR article about a verticle set of shelves that could store locos and slide up and down to deliver locos to the layout at table level. Can anyone help me to locate the article?

If you flip through any recent issue of MR, you’ll find an advertisement for a train elevator system.

I have not been a subscriber for long (only about 10mos); so I can’t help you find any articles about it. But I remember seeing this ad in almost every issue so far.
