I would like to say thank you to those who have sent in comments so far. Here is one of the first comments I received from passenger Hari:
"I take lightrail connection to Mountain View at Great America station and there is at the most about 4min of gap. I often miss the immediate connection for various reasons such as, - the ACE train is late - the shuttle driver is lethargic that day, - passengers don't settle down quickly etc., but in all the four occasions that I used ACE in the last 2 weeks, thanks to ACE being on time, I managed to get the immediate connection saving 15min of commute (the frequency of lightrail service). Good to know about the improvements in signal system, I have a hope that this will continue."
Thanks Hari for your feedback! I encourage all of you to continue sending in your comments and I hope to hear from you soon!
