Hey, any chance at getting a fluid version of this?
Reason being, pumps don't work on fluid wagons that don't have a locomotive attached to them. (Even if aligned correctly, even if using mods that increase pump tolerances)

I want to do a viable play through of dropping cuts of cars in yards and having only a few locomotives with a lot of cars. However, dropping off fluid wagons is not possible due to the above issue.

Could you provide some save file where I can see what you are planning, onegaishimasu?
Bulk Rail Loader are like fluid wagon for cargo. So fluid wagon is already bulk, actually.

Hey ixu, I dont mean to necro the post, but if I understand him correctly I was kind of thinking the same thing. where you can preload a tank (above) the rail system, Much like this has an internal storage that loads itself. maybe a new item that uses pipe connectors with an internal tank to preload while waiting on a locomotive.
