I see the conversations regarding overnight parking at Lansdale/Colmar...and see that traveling by train to Washington DC from these stations appears simple. Question is, in which stations will I need to switch trains? Thinking Colmar to 30th Street, then direct to Union Station in DC, where I will want to transfer to King Street Station near Alexandria VA...as I'd like to stay in a hotel very near that station. Am I thinking correctly?
Further, can I buy a ticket that will get me trough all stops? or do I need to buy one for each leg--Colmar to 30th street / 30th street to Union Station / Union to King Street.
Finally, is buying them at the ticket windows the way to go, or can I buy them on line ahead? I am simply concerned about on-line purchases, in case I end up reading the schedules incorrectly.
Appreciate any thoughts.
