I found the New Hope Valley Railway about 10 years ago and after that the Christmas train has been a part of the season for our family every year.
The tracks are only used on ride days and are fenced away from the public area, that you should be in.
There are old Diesel Locomotives, Steam Locomotives, and other Rolling Stock on display, as well as the museum. You can ride the train on the first Sunday of each month from May through November. December will have 3 Christmas Train Weekends. A garden train is set up on the site also. There is no charge to view any of the equipment or museum, but there is a charge to ride the trains.
To verify your find email me the builder's number for engine # 17
