D. Dad's trains.

Our family is friends with another family, and they have a little boy about 6 or so.  He loves trains.  Dad got to thinking about this, and got out HIS train set for said little guy to see (and play with).  I hadn't seen it in action in years, if ever, and so I joined them on "Train Day".  There was no shortage of cars, there was both steam and diesel styles, and lots of noise.  It was so cool, and the little guy was just nose to track watching the cars go.

I joined in later.  I found out that Dad has it set up so you can turn the cars around via a loop on the inside of the track, it is an 027 size, his sister put oil in the part that makes smoke, (and it did for a looooooooooong time)...

And when Dad was a kid, he told me he was a bit of a poop one time, when the house cat Blackie fell asleep on the tracks, Dad kept running the train up to him and blowing the whistle.  Blackie would try and go off the board the other direction, and Dad would run the train over to that side and blow the whistle.

Blackie then knocked the train off the tracks!
(Sorry, Dad, but Yay, Blackie!)

Several of the Lionel cars.

The diesel pushers and some other cars.

Dad's holding the repairman car.  The little man turns which ever way the car goes,
and can bump, then go the other direction by touching the bumpers on the ends!
