Changes

''"Renovate" means just replacing with an engine of the same model as the old one (where you pay a reduced cost instead of the full purchase cost). You will often find Even if the train you wish to renovate is an old model isntrain, for renovations '''it is always available''' even if you can't available any morebuy it in the depot as a new train anymore. However; you might decide, that you want to replace it for a newer model instead, and thus that your "renovation" turns into a "replacement". Both terms refer to the exact same procedure, however.''

** If you've selected a different model, it will be considered '''Upgrade/Replacement''' and the cost (and stat differences) will be shown between those two lists

* If you play with single depot, the train depot area might get really congested if you send some 10+ '''[[Trains]] ''' to replace all at once. There is usually no such problem with even large volume of ''[[Road Vehiclesvehicles]]. Hint: You're not really limited to a single depot, only that all rail depots must be adjacent to each other. (The vehicle depot can be built elsewhere) You are therefore highly recommended to build a "cluster" of depots and use routing to make sure all trains don't try to reach the same one at the same time (they go for the closest one)'.* This screen is built on the assumption you will just want to renovate/replace the engine, but otherwise keep everything the same. This is, however, often not the case. If you want to add more cargo cars to take advantage of a more powerful engine, for instance. Or if you otherwise would like to examine your trains once they have reached the depot. In such cases you have to send engines to the depot yourself..manually rather than using the ''Replace'' window.
