Look like sparky got the link. Where that sign is located is likely where there is a straight through route and a diverging curved route that's not used often and is used at low speed.
I'm not really a spotter, but there's a whole bunch of "o" trains running around the upstairs in what should have been extra bedrooms :-)
I think it may have something to do with a train switching tracks to change direction...just a guess though...:)JP
ReplyDeleteI had no clue! Had to look it up.

you find fun stuff . . thanks.
ReplyDeleteI don't know but when you find out, Vic, let us know.
ReplyDeleteWe need more folks like Sparky around so we don't have to wonder about things.
ReplyDeleteTCF, it seems Sparky and Brigid got it right. A Jump Frog is a mechanism that causes the train to switch tracks.
ReplyDeleteI still think the sign is too funny though!
