At what point do you consider a train to be old?

For me personally from 25 to 30 years.

However, this does not matter, because even old rolling material can work perfectly – often more reliable, though not as efficient as current rolling material.

As an example, we take the old building locomotives, which still serve daily. Almost the entire DB single locomotive family is still represented on the rails, although today in other colour dresses with private railways. Approximately the series 110, 112, 139, 140 and 151. Their successors, the series 111. Or in the diesel sector the series 218, or V60, V90, V100. The 420 or 628 series in the drive car range. Even the ICE 1 is now “old”, even the ICE 3 is increasing.

And other classics have also done their service for a long time, partly because they eventually divorced, among other things, because the austerity course of the Bundesbahn allowed them to drive on wear. The example is the 103.

I also understand if rolling material is sorted out for reasons of efficiency or because of ongoing technical problems or lack of accessibility. What I don’t understand is sorting out on the basis of age. We are now driving cars on the parking track or demanding new vehicles, although the age of vehicles is just 10-12 years. This has nothing to do with efficiency, neither financial nor ecological.
