Automatic Scanning 159.810 - 161.565

Hey railfans, hate to sound like such a greenhorn, but I'm having trouble understand scanner basics. I'll keep my question simple and direct:



Q: I want my radio (Baofeng Uv-5r) to scan the entire range of 159.810 - 161.565. So do I have to enter and save every single frequency in between that range to my memory, or is there a way to make it automatically scan between two requency ranges?



Thanks for any help...hopefully with a little help I'll be listening to the local train traffic tonight.
