Strasburg is a fantastic RR hub of High Iron destinations made even more complete three times a year with the 0 scale train show.
Strasburg is home to the National TCA headquarters which houses the history of model trains, literature and display layouts. Right next door is one of the largest present day collections of cabeese in which you can spend the night.
The Choo Choo Barn & hobby shop with a decent sized traditional gauge layout next to the PA museum.
Not to be missed is the PA State Museum 100,000 square foot indoor collection of some of the most note worthy 1:1 examples of RR development over the years. Plus acres of out door engines and equipment spread around a beautiful TT.
Of course the star of the location is the fully functioning Strasburg Steam RR. Come and smash the few pennies you will have left over from the train show/swap meet under live steam.
So arrive early and soak in a weekend of RR enjoyment. After the Strasburg fire house 0 scale show there are hundreds of outlet shops for stalwart shoppers.
