Actually I never knew that so much detail and variables went into reliability before coming across this forum :)

I never knew about that bug so either I've been lucky or I've not been paying attention to a few trains no longer earning revenue (which doesn't always jump out on longer routes) I remember there are a few cases where I'd let my trains run for more than 25 years simply because no better model becomes available in that period. One example is running non-electric tracks with the GP18 which outperforms most newer trains for the next 20 years in terms of reliability, speed (especially at grades) and yet reasonable running costs. Somehow those 25 year old engines still run with a 1-2% breakdown chance...

After several years without RT II, I've finally picked up the platinum edition... I usually replace my trains based on "the numbers", looking mostly at the chances of breakdown and overall speed. And of course how much cash I have on hand, which seems to be quite the bottleneck in most Second Century campaigns.
