How in the heck can MARC go to Virginia until Long Bridge crossing is expanded to 4 tracks? Capacity is listed as at 98% of theory during rush hours on the CSX line. As well how can Brunswick trains even make the transition just north of US until 1st street tunnel is expanded to to connect under the present tracks 5 - 12(?) ?
With PSR, is long bridge still at capacity? I'd assume it means fewer CSX trains running over it. Also, does the coal for morgantown come from south, or on brunswick line? Either way, that will dry up in a few years.
It looks like there is currently a single track from the south/east bound track on brunswick line, which seems to also have a siding for VRE consists to rest off of it.
Putting in a connection directly to the northbound track, crossing over the southbound is a must.
(The camden line needs similar, it looks like over a mile of single track running, to union station from the junction)
If runthroughs were done, some of the tracks currently used for staging would no longer be needed.
A bigger issue is that they need integration into a regional rail system, instead of rush hour commute system, as that pattern of use likely isn't coming back.
1st street tunnel is what, 6tph now?
I imagine even 2 runthroughs per hour would get used.
of course, ultimately, DMU/EMU which could use either high or low platforms, with a single crew member would provide best coverage, for that level service.
