First you need to go to the iSilo website and download the iSilo reader
http://www.isilo.com/download/iSiloPalmOS.htm
then go to the UP home page and sign in, then use this link to download to your hearts content:
https://employees.www.uprr.com/admin/lo ... ds%2eshtml
if that link does not work, in the search box on the UP employee web page, type in gcor download, it should direct you to the download page.
Also, myrulebook.com is no longer working, but he gives a tutorial on the whole thing for you as well:
