CTA rider: I want longer trains for games

Ernesto Cano of Lincoln Square wrote to "Going Public" with a question about the types of trains that service events. The CTA response is after the jump.

"Who determines when to send out four-, six-, or eight-car trains from the CTA terminals?
 
Whenever there is a late or midday Cubs game, I think it is awful that the Brown Line runs jam-packed, four-car trains, when in all seriousness, they should run eight-car trains. It's been unsafe the few times I have been a 'victim' of the four-car trains during a Cubs game.

Same thing has happened in the early evening to me on the Orange and Brown Lines, where people are crammed like sardines at 6:15 p.m. on a four-car train at the tail end of rush hour.
 
Can this issue that has turned out to be a pet peeve of mine be improved and send more trains during peak events and extend daily peak hours (including Bears games, Grant Park events and conventions)?
 
P.S. Service was excellent and more frequent in the early evenings on the Red, Orange, Pink and Brown Lines while the Taste of Chicago was going on."
