came upon this thread while looking through old posts. am surprised there have been no replies.
I operate using RAILOP which I have found to be a terrific program.
if you google railop you can get to the site and can download a demo
program to get an idea how it works.
there is also a yahoo users group which is very friendly and can answer any questions you may have.
all messages can be read without subscribing but to post you must subscribe.
I operate on my own and started with a small layout and find that RAILOP can be used with a layout of any size.
it is nice to operate with a switchlist and not have to juggle a lot of cards.
hope this is of some help
