Good Luck!
I have been looking for the same thing and emailed Tayden Design about their Gallery Works and All Aboard programs. A reply back from them said they both were compatible with Vista. I haven't tried either one yet but they told me you can download a demo from their website , tayden.com
I use Microsoft Excel.I made my own inventory list, that shows car initials,car number,type of car,load it carries,industry(s) served,if it is a private road ( ie-Quaker Oats),and whom the car is from...ie-Wathers,Athearn,etc.If anyone is interested in a sample copy of what my list looks like..let me know.
