How many hobby shops or train stores are in the bay area?
They should have charged you for 4 questions here. To find the train and hobby shops in your area, go to Google and click on the word Maps. Then, type in “model train shops” and your town or area. It will show you where all of them are. Amtrak costs so much because it costs them so much to run a real train. Trains are huge and require tons (literally!) of fuel. You can get someone else to answer the other two questions. You might want to relist those other questions in the Travel category. If you do, it will cost you 5 points, but you will probably get better answers.
