If the region does not strictly prohibit bringing baby strollers on high-speed trains, then mothers can bring strollers on board. However, strollers come in various sizes. If you want to bring a stroller, it is best to consider whether your stroller can fit into the train carriage aisle. If the stroller is too wide to pass through the aisle, it is better not to bring it on the train. The stroller can be placed in the aisle after the train starts moving, allowing the baby to sit directly in it, which is convenient for mothers to take care of their babies. If there are too many people and there is no room for the stroller, it can be folded and placed on the luggage rack. If the stroller cannot be folded, you can communicate with the train attendant to see if it can be placed in a carriage with fewer or no passengers.
