In Marion, IN, there is an old railroad depot along an active NS line that currently has a Mexican restaurant inside. Outside is a sign placed by NS that talks about it being a former narrow gauge railroad. Is this the PRR 3 ft gauge line or something else? I'm assuming it is because there is a color position signal just down the line from the depot but I wondered if it might have been a PRR predecessor in the area or the actual PRR narrow gauge. I think this line is running north/south but I'm not positive of that.
