Questions about Railroad Tycoon 2

[Phlegmak]

I have some questions about RRT2.

1. One station produces Grain and also demands it. How do I transport grain to itself and profit from it?

2. What do the numbers mean that are next to the engines' names? Like 4-4-2 Ironhorse or something. What is the 4-4-2?

It's been a long time since I played, but in most of these games you can drop off the grain at another station, then carry it back. It *might* have to stay there a day or week or so to reset its "from".

The 4-4-2 is the way wheels are arranged: http://en.wikipedia.org/wiki/Whyte_notation
