When a mine runs out of ore or a sub-factory becomes obsolete I'm left with trains. It would be nice if I could just send them to a Train Deconstructor and it gets removed.

The Train Deconstructor would need to have a building that acts as Train Stop and others that just deconstruct locomotives and wagons. The later would basically just be chests (or pairs of them).

When a train stops at the Train Deconstructor the fuel from the locomotives and any remaining cargo is put into the deconstructor buildings. If the train is empty, i.e. everything fits in the chests, the train itself is removed and put into the deconstructor buildings. Keeping train parts and fuel/cargo separate might be nice but would also be trivial to separate manually. For fluids I'm afraid the only good solution is to destroy them.

The only thing that I believe would require a bit of extra work would be handling the chests overflowing. If a train can't be unloaded fully then you have to check every second or so if it can be unloaded now.

found this today and after reading through the info on the mod I thught the same as mrvn did.

Why custom parts to build trains? and a deconstructor would be nice.

My first thought was combo this with logistics train network mod to remove the need for depot stacks, instead build and deconstruct trains as needed, making train depot footprints on the map much smaller.

I like the idea, and have already envisioned how to use it in my factory.... but... The train parts and train fuel could probably be completely removed as concepts. Just make the builders into specialised assembly buildings. The cars are built from the standard recipe, using normal methods, and the on-rail placement rather than into chest placement is the main difference from an assembly building. Making a "mod" to the assembly building ought to be easier than making new items, new recipes and everything else. Deconstruction "burns" all wagon contents, fuel could be saved. The mined cars become inventory in their respective machines, ready for placement on the next build order.

I would use chests instead of assemblers. We can already build locomotives, cargo wagons and fluid wagons. Just insert them into the train construction buildings as is for placement. That's the only way I can see the train deconstructor be useful. Without a way to re-insert the deconstructed train to be re-constructed somewhere else there would be little benefit.
