After a few months away playing Minecraft, I am shifting some attention back to long-time favorites like RR Tycoon. It has been quiet around here without my agitation, so I'll try to stir the pot.
My question of the day (or maybe week): At what age do you like to replace your engines for the sake of age alone (i.e. even with no new tech)?
How long might you stretch an aging batch of engines to catch a new type you know is about to be introduced? Do you "run the numbers", or do you "have a feel"? Does the tedium of replacing engines for a large number of trains affect your decision?
