it would be fun to have weekend service. My nephew loves the trains, however i cannot take him during the weekdays because of him having school when i visit. I love going to visit Union Station & watching the trains.
i think they should @ least have some service on the weekends on the Penn Line from @ least Baltimore's Penn Station to DC.
Maybe if they were to try & promote the service like offering free rides the first week or something that might possibly warrant people to want to ride the trains.
They could work in conjunction with businesses in DC offering discounts if the people showed their MARC train passes or something like that. It would be worth a try.
Like the commerical "If you build it they will come."
Just a thought...
