Longer train consists? ... Trains that are longer than you platform provide dwell times that grow exponentially.
So why not lengthen the platforms and build the extensions as high level? There looks to be enough room to lengthen Rydal, Meadowbrook,Trevose and Yardley to 6 car length platforms, as well as converting Crestmont . I'd think that even lengthening every single station to at least 5 car lengths and converting them to high level platforms has to be cheaper than the $150 million price tag.
With that said, I'm not familiar with the rush hour consists on the Warminster and West Trenton lines. About how many cars in length are rush hour trains? Are my idealized platform lengths long enough, or do they need changing? Also, ideally, am I correct in assuming that you want all the platforms on a given line to be of equal length?
Upgrade existing stations to HLP and increase parking? ... How many stations need to be retrofitted? What is your breakeven if a single platform, 4car HLP costs 2-3mil (Cheltenham & Olney on R8 line). What about that parking garage at either Glenside or Jenkintown
All projects that will need to be done anyway. As gas becomes more scarce, more companies will move into the city in order to be closer to transportation hubs. This means more commuters, which will mean longer trains. Better to do it now, if for only the ability to have longer trains when needed.
Recreate a line to supplement existing corridors? ... Newtown trains do not need additional slots on the Reading trunk. HLP will be required for any new stations, and the Fox Chase branch is being rebuild as 4car HLP as we speak. Rebuilding the Newtown Line does not place service disruptions on the rest of the Reading Lines while it is being built.
I still say the best way to restore service is the Newtown Dinky. No new slots on the Reading main needed; the possibility of using the R3 not only to go into the city but also for radial service to West Trenton; certainly a lower price and certainly less Montgomery County opposition since so little of the dinky ROW would reside in Montco. I think radial service is such an overlooked part of public transportation, and a connection at Bethayres would provide for such service. Again, this is not an issue if SEPTA's other service gaps were already being fixed...which would've happened if SVM had been a rational, workable plan...and a rational plan would have meant FTA funds, which would have freed up funds for R3 West Chester service restoration...[/lament]. Anyway, Felix is right - not everyone who creates congestion is commuting; some are simply visiting friends in Jenkintown. So why do ALL routings have to go into center city?
