I think most people have already said what I would suggest, but if i were starting out I would definitely go for Tomy blue track. As already said it has the largest range of accessories/scenery parts, is the most compatible with most engines and is the most flexible being compatible with many things Trackmaster is not including PlaRail Advance - something you should consider if you like 'real world' trains as opposed to just Thomas.
The other advantage is that you can often pick up nice job lots or bargains on eBay or from charity/thrift stores or car boots/garage sales as often evidenced on here. You'll also find the older Tomy engines are built with a far greater level of detail and realism than the Trackmaster ones and that there is ultimatelly a much larger range of models available - doubly so if you go outside of Thomas only.
But the most important thing is HAVE FUN!!

Happily collecting things all my life...
