Yeah some train cars do have a dedicated spot for bikes and bulky stuff, even with a little bike sticker on the door to label them as such. But It still comes at a big cost. I'd say in the space three people with three ebikes can fit, you can probably fit at least three times as many people standing and hanging on the pole. Plus in the chaos of the few seconds the train waits with the doors open they can be a hassle and are sometimes even a source of door delays moving past people and unloading all this equipment.
