I don't know if this has ever been kicked around, but another way to streamline service on RI is to add an off peak element to the rush hour practice of keeping the Blue Island local service via Beverly seperate from the Joliet service via the main line. It could be done with the existing equipment, actually, only one more set would have to be added to the midday runs (3 for Joliet, 2 for BI under the new arrangement vs. the current 4 midday sets), and due to the greatly improved turnaround times, it would enable the Joliet equipment to make at least 2 round trips. An example of a revised schedule would look something like this:
Midday:
Outbound trains to Joliet departing LSS at the :00 of every hour from 8am-2pm
Outbound trains to BI departing LSS at the :10 of every hour from 8:10am-2:10pm
Evenings:
Outbound trains to Joliet departing at 7, 8, and 9pm
Outbound trains to BI departing 7:10, 8:10, and 9:10pm
From 10pm onward, local service to Joliet via Beverly as is done currently. And if this particular schedule was actually adopted, the inbound schedule could stay pretty much the same in terms of actual station departure times, although a different service alignment would be in effect. This arrangement is most efficient with scheduled headways of an hour or less, which is why it might not work on weekends, since the headways are still 2 hours for the most part. But the biggest benefit would be that at least during the week, most off-peak passengers traveling west of Blue Island would be freed from the slow, agonizing grind of riding the slower local trains, and save up to 15 minutes on their journey in the process.
Thoughts?
