Does what you want - makes the cityrail timetable page usable.

It'd be nice to inject a dropdown on the page to select a from and to station rather than having to type them in as uri parameters, and it seems to me that there's a bug in highlighting stations with spaces in their name.

Last improvement would be to keep the am/pm information in each header.

5 stars when 2/3 of the above are fixed (I'd do it myself but I've got a stack of writing to do so no time to learn greasmonkey for 4 months or so ... )
