Memorial Day sales....

One more question. What set did these two come in?

I can pair up all of the remaining rolling stock with the engines you've got for you.

The Ice Van belongs to the R/C Thomas to make the original version
The Green Van goes with the regular Thomas
The Blue Brakevan goes with Percy
The China Clay Troublesome Truck goes with Ben
The empty Troublesome Truck goes with Diesel 10.
All of the engines (with the exception of R/C Thomas) would have also come with those half straight track pieces you've got as well.

It looks like you've got the Pack of Track as well, as I'm able to match up the pictures of the track and road with the contents in that pack. Here's some more information on it: http://tttetrackmaster.wikia.com/wiki/Pack_of_Track
