I was impressed with seeing the crowds on the Valley Line yesterday. I believe they were running every 10 minutes, all 2 car trains. The way the process works apparently for TransEd's level of service, be it frequency and/ or train length, is that the City puts in the request in advance for the level of service they want (makes sense, as it's the City that is then paying for the operation of those trains). The contrast between the Valley Line and Capital Line due to train capacity was noticable. ETS went with 15 minute service, but 5 car trains on the Capital line. Due to limited capacity of the Valley Line, they had to go with 10 minute service with all 2 car trains. A 2 car train is about equivalent to a 3 car Capital Line train. Personally I think ETS should have had more frequent service on the Capital Line, but, I believe 15 minute service is generally par for the course on New Years Eve.
