SOLVED. Children's picture "board book" about trains had a moveable RR Signal

[Buster]

When I was young we had a board book I think about 4" by 9" to 12" that had a moveable RR signal on the back cover. The front cover was a locomotive and each successive page was a different type of rail car. Each page started off with "Clickety-clack, clickety-clack" such as "Clickety-clack, clickety-clack, what's the next car on the track? Now we move the signal. First red, then yellow, then green. It's a box car!"

Train Time?

Clickety-clack, Clickety-clack.
The train clacks down the railroad track.
Full of people or full of supplies,
the train flies over the rails and ties.

No, the book itself was more long and not so tall. With the binding on the left on the short side of the book.

Another one of the pages was:
"Clickety-clack, Clickety-clack, busy day on the tracks. Now we move the signal. First red, then yellow, then green. It's a [tank?] car!"

Last page ended with "What's the last car on the track? It's a caboose! Wave to the conductor and give him a green light!"

I guess you would call it a "shape book" - sort of like The Train Book by Jeffrey Victor https://www.goodreads.com/book/show/1.... It was a full-color book and the engineer shown in the locomotive on the cover had the typical striped engineer's cap.
