Antique achievement questions

[Stormmaster]

Keep a train built before 1900 running until the year 2000. What exactly does this mean?

1. Does it have to run continiously without going to depot? Or the criteria is simply that after reaching 2000 you have an old train on the line (regardless of how active or inactive it had been the whole century)?
2. Does all of the train have to be built before 1900? Will newer wagons spoil everything? Or maybe it is even enough to have just one old part (the same way as overall age of a train is detrmined)?

Please share your experience.

Hi Storm,

I got the achievement by putting an old engine with passenger cars in storage after replacing it with a newer combi.
A few years later (2000 something), I've put it back out on a passenger line, and before it finished the whole line/route, I got the achievement.

You can also buy a loc. + wagons, just before it goes out of date, and leave it in storage. Then around 2000 you put it out on a line/route.

After getting the achievement, you can sell the antique combi.

Cheers!
