Speedometer for 1/8 scale railroad

ok, taking all the suggestions into account, what board would you recommend I start with, in order to have a two line LCD output, that uses either a rotary selector or a push button to cycle through various outputs with a header on the first line, and data on the second. For example:

Speed
4.2

Scale Speed
33.6

hours
24.6

I would like to be able to capture and display two different speed values, two cumulative distance values, two trip distance values, and an hour meter (based on when a motor is turning).
