And now, it appears, Amtrak’s final answer is a “no.” DDOT cannot go under the Hopscotch Bridge, cannot put a railyard near Union Station, and cannot connect directly to the future north Metro entrance.

And so, on to Plan B. DDOT’s new plan will locate the streetcar railyard on the east end of the line somewhere near the Anacostia River, and will send the streetcar over the Hopscotch Bridge to a loop on the upper deck of the Union Station parking garage. (See an image of the route plan here.)

The new Union Station stop will be less attractive to riders transferring to or from Metro, but it will make transfers to Circulator buses and Amtrak, MARC and VRE easier. It’s a good enough solution, given the context.

One question I have is how this new layout will work when (if) DDOT eventually extends the streetcar towards K Street and downtown. Is the loop just a temporary solution?
