    In previous years, the carriages produced were all in-line toilets, and in recent years, new carriages have begun to use vacuum toilets.

    Now the new train bodies will be equipped with environmentally friendly vacuum toilets;

    Some of the older car bodies will also be retrofitted when they are returned to the factory for repair.

    Due to the relatively large number of old-fashioned inline trains in China, there are fewer sewage suction equipment at the station, and the sewage suction equipment and the installation of toilets need to be carried out gradually.

    So there are still some non-collection bikes in operation, but the number will gradually decrease.
