IMO it is a toss up between the new Gateway tunnel bores and new B & P bores. Both projects have to have 2 bores each in service to allow for the required cross passageways ~ every 800 feet for emergency evacuation. Either tunnel with a present failure will be a disaster but B&P can probably be temporarily restored faster?
Now IMO next will be starting the Long bridge 2nd bridge . Mainly since the final EIS is done and contracts to start work may be quickly initiated. B&P may take somewhat longer to start ? Additional service can start to Richmond as soon as Long Bridge is complete?
Rather that having 2 bores for the 4 a week diesel double stacks of NS, just give them trackage rights and restored connections at Orangeville and Claremont to the just rebuilt CSX tunnel.
I still think ground up reconstruction of the B&P tunnels (without having to rush for trains) for MARC, to have connections with subway and light rail, would make more sense, long run.
at the same time, having even 2 tracks with 60MPH MAS will make all trips faster and more reliable.
and then 4 tracks, Balt to DC.
I thought there was 2-3 additional slots currently not used for long bridge?
