I currently commute from Irvine (Woodbury) to Pasadena. Before that I commuted from Irvine to Downtown LA. Have done it for a couple of years now.
I used to drive to LA but the 210 freeway makes impossible to drive to Pasadena. Now, I take the Metrolink everyday.
Drive to LA is about 1 hour (one-way) with no traffic (once in a blue moon or if you leave your house at like 4 a.m. and come back after 8 p.m.), about 1 hour and a half on average (if you leave like 6 a.m. from Irvine and like 7 p.m from LA) but can get up to 2:15 (once every couple of months.) Those times are getting longer because the traffic starts getting bad in Irvine starting in Jeffrey now.
As for metrolink:
-Pros:
-No driving!!! Saves a lot of stress and allows you to plan your day better. It can be late some times but pretty reliable. Amtrak on the other hand, a complete different story. Big plus.
-Meet cool people. While many people on the train keep to themselves, you can find some really nice one during the commute (esp. in the mornings). I play cribbage in the morning with a bunch guys and it makes the commute fly by.
-Free time: You get some free time on the train. A lot of people have laptop, everyone has an ipod. I usually read and to try to catch up on some sleep. Although, I can't really sleep on the train because it rocks some much but others do.
-Cons:
-Schedule:
-Pretty good schedule during rush hour (between 5 a.m. and 10 a.m. and 4 p.m and 6:30 p.m), one train about every half hour to an hour. However, no metrolink trains during the middle of the day or after 6:30 p.m.
However, if you buy the monthly pass, you can take the amtrak and that allow you to take later trains for free(8 p.m. and 10:10 p.m.) Amtrak also has trains in the middle of the day. If you don't have a monthly pass, one-way trip from LA to Irvine is $13 (pretty steep for my taste)
-Time:
-Doesn't really save you time, from my office to home, it takes about 2 hours. (e.g., 5 p.m. out of work about 7 when I step in the door at home). That may mean that you don't get home until 11:30 p.m for the last train.
-Since I work in Pasadena, I have to take the Gold Line (LA metro system) to Union and then take the Metrolink. That means that I have to leave at least a half hour early. For example, I have to leave my work at 5 p.m to get to the 5:40 Metrolink (which includes a 5-10 minute walk from my work to the Gold line station). If you work in Downtown LA, it's not too bad since red line runs quite frequently and its only like a 5 minute ride to union station.
-You also have to allocate extra time to be at the train station about 5 minutes earlier. Obvious, the train won't wait for you so if you miss it (even by 30 secs) you have to wait for at least half hour for the next one. Trust me, getting from you car to the train platform takes longer than you think. I usually take the 5:33 train in the morning and I have to leave my house no later than 5:15 (10 minute drive, five minutes walking, 3 minute buffer). You get used to that kinda of plan if you start taking the train.
-Convenience:
-You basically stuck once you get to work. It's not a problem for me because there is quite a lot of restaurant and stores around my work. However, if you need to go somewhere for work. . .you're out of luck.
-Even:
-Money: A monthly pass from Irvine to LA is $228. You get to ride on the public transits in LA and OC for free so no extra charges.
That comes out to about 11 bucks per commuting day. Depending on the type of car you have and the gas mileage you get, the train is probably a little cheaper (90 mile commute).
Daily Roundtrips are $15 a day while the 10-trip pass comes out to about $14 dollars a day. You do the math.
-My take:
-If you have pretty good hours (i.e 8 to 6) you should take the train. It's much less stressful and you can rest a little. It somewhat cheaper and you don't have worry about much on the train.
-If you don't have good hours, you may find yourself stuck at work because the trains have stopped running for the evening. Also, the train schedules are unforgiving-miss it by a second miss it for a half hour.
-I like the train (even though I have crazy hours) because of the less stress.
I hope that helps. I have to say that the commute (whether by train or by car) gets old real fast. I spend almost no time with my wife on weekdays (leave the house at 5 a.m and get home usually around 8 p.m.) It's even tougher with kids (don't have any yet). The train helps but still. . .
