Coaster has no major plans for the future. With TransitAmerica taking over operations next month there are some schedule adjustments being considered, but no new equipment purchases or lines being considered.
Now, as far as lines ARE concerned there is rumor that a local government entitity wants to build a Freight line connecting Chula Vista Border crossing to San bernardino via El Cajon, SR67, Escondido, and the I15 (paralleling the roads). It's pure speculation, but If this line were to bear fruit it's possible Coaster could come up with an East County line heading North-South stopping in
Escondido, Poway, Lakeside, El Cajon, Spring Valley, Lemon Grove, Chula Vista.
The Coastal and East County lines would be connected East-West with the Trolley (Orange and Green lines) and SPRINTER. Similarly, new equipment would have to be purchased, but this is at least 10-15 years away if it ever comes to fruitation..
Now, for the impending stuff (That is actually on the drawing board)
Herzog has reviewed the service and rumor amongst employees is that Friday late night service could be expanded to Saturday as well, and 657 which leaves Downtown San Diego at 9:45 PM will run every night as opposed to 659 which runs game nights only at 10:15 PM, I don't believe day service is to change
