help for the helpless

I have been studying train schedules on line and trying to determine if there is any way I can go from Colfax to Bakersfield - and what would it cost? So, I started filling out a form and messed up immediately - and so I tried to determine how to undo the mess up and failed - so I was frustrated and departed the train schedule. I know I would have to change trains in Sacramento. I would probably go on this journey in July and perhaps be gone 4 or 5 days. Anyhow, if any one or all of you would tackle this and then develop a simple step by step instruction sheet - I would be so grateful! My hopes are high! m-g
