Taipei to Kaohsiung?

Looking to get to Taipei to Kaohsiung on a weekend to visit some friends. I checked the taiwan train website linked in the sticky above but could not find trains from Taipei station to Kaohsiung. Could someone recommend me a good route to take? Thanks. Also, I see the HSR ends in Zuoying. Can I take a bus or train from there to Kaohsiung?

Try here for the trains.

Zuoying is where Lotus Lake is located. It’s about 5km or so north of Kaohsiung train station. There’s plenty of local trains you can take between the two, or a taxi is only NT$150 or so.
