As you've seen on this thread others do have some experience with setups similar to yours. I don't have a test lab with a range of test machines in it.
If you don't know which components your machine has Belarc works well

The size of the monitor isn't relevant but the pixels are. 640 by 480 has 307,200 pixels,
1920 x 1200 has 2,304,000 pixels so roughly speaking you need a machine 8 times the power to give the same frames per second. You can lower the resolution or run in a window but that lowers performance as well.

Will give you some idea of the cpu performance. If you go with TS2010 that version shifts more work down to the GPU

Will give you some idea of where your graphics card is in relation to others. TS2009/10 do use DXT compression so the 256 mb of graphic memory won't be quite such a drawback as it would with earlier versions.
TS2009/10 can make use of up to 4 gigs of memory under a 64 bit operating system, WIN 7 likes 512mb - 1 gig so pushing your memory up to 4 -6 gigs may help.

There are performanc / graphics trade offs you can set in the game, for instance the default distance is 5 kilometers you can drop this down to one, which means Trainz has fewer objects to keep track of.
Choose your layouts and assets with care, some are much more demanding than others. Content is made by many people and some are a lot better at making good content that runs smoothly than others. The S&C team have created some very nice content that runs reasonably well.
www.settleandcarlisle.co.uk and at the end of the day Trainz is all about content.
Summation It will probably work enough for you to get a taste then you can decide whether to upgrade your hardware if required or not.
My recommendation would be buy TS2010 and the S&C add on and try it. Its cheaper than buying new hardware and there is a reasonable chance it will work.
