Well sure, its evident that they are early because of the dark blue color but exactly what engine or engines were made with as a side cogwheel train to engage those teeth which are on the outer portion of the slopes. 1989 with the rounded Tomy Logo are stamped into the underside which also brings to light that these are not reversible like the currant slopes and are parts A & B for connection purposes.
Leyland, have you seen any Cog type Tomy trains that may be vintage? I wonder if they are from the friction motored era. My guess is that the drive wheel has an additional gear wheel on the outside of each drive wheel with a smaller circumference so the gear would clear the sides of the normal rails. Very curious..
EDIT EDIT EDIT
EUREKA! And here it is...Wow, is this set every big, the biggest I have seen with just about every gimmick included.
A great video and there is even a Shoutout to BluePlasticTracks.com near the end
