Cars like this 46331 Swiss hopper still have a ladder: https://img.ricardostati...x1350/pl/1190099776/0/1/
So does this Piko Tank car: https://az95169.vo.msecn...es/piko/large/L54795.jpg

I am sure that there are other car types which still have such features, where hatches or other equipment must be accessed from the top for loading/discharge.

These coaches and the ones in your first post in this thread would only have had the roof accessed while in a service facility siding, to allow someone to go and refill/replace the lanterns that provided lighting. I doubt that such sidings would have had catenary, as the locos shunting them would be more likely to be steam or diesel.

In the case of the electric loco you pictured, it shows it hauling freight, and it is described as a freight loco, but even so, in the shunting yards they would more likely have non-electric locos shunting any rolling stock.

The tanker and hopper wagons linked in another post would also likely have personnel climbing the ladders only in loading/unloading facilities, again most likely devoid of catenary. To load the hopper wagon it needs to run under a shute where catenary would soon be damaged by whatever product is being loaded, and someone would only need to climb the ladder to check the load while such operations were in progress. Similarly with the tanker, fuel depots would not have catenary due to the risk of electrical sparks igniting fumes. Even of the load is non-flammable, such facilities tend to be devoid of catenary for practical operational reasons.

very nicely done.
