My only chance stop by was on a week day when no operations were going on so I checked out the grounds and equipment anyway.
For not being open there was only one spot in the small lot left which was weird, what's it like when they are open. The property is pretty nice with lots of green spaces with picnic tables to make a day of it. There is static displays with various railroad equipment from cranes, passenger cars, cabooses, locomotives etc. There is a ticket passenger station and a tower over looking the rails with a huge shed that has cars that you can go in when they are open.
Even though they are only open on weekends for train rides you can go during the week with the kids and have a picnic and walk around looking at the equipment so if your driving by it is a nice attraction for the kids.
