Hey there folks. This summer I'm heading out to the West Coast. Before I head back to school here in the Midwest, I'm wanting to end the summer with a bang by taking a train. I've had great experiences on the one from Oklahoma City to Fort Worth and taking a train on the coast would be something else. Would it be possible for me to have a day or two layovers in cities such as San Francisco, Portland, and Seattle? What would be the cheapest, most efficient way for me to make this trip happen?

Thank you guys for any advice offered. I sincerely appreciate it.
