Question lubricate track?

I have a Liftmaster Model T industrial duty door operator. I am wondering if I should be lubing the part of the track that the trolley carriage slides on when the door opens and closes. After lubricating the rest of the door/operator I still hear a considerable squeal and it seems to be coming from the trolley carriage.

Attached are some pictures of the trolley carriage and the track. Does the metal slide against metal when the door opens and closes?

I would, metal to metal just causes wear.

A dry lube to minimize dust & dirt collection!

I would definetely lubricate it. I can't tell from the photo if you've already done it but I also lubricate the spring as there can be a lot of friction between all the turns of wire in the spring.

I've always heard to never lubricate the rails but I wasn't sure about the track.

Yes put a light coat of grease on top and bottom... Garage door track, NO!
