Are pets allowed on Chicago L trains?

Chicago L allows pets on its trains, but there are specific guidelines that pet owners must follow. Generally, small pets are permitted, provided they are contained in carriers that can be held on the owner's lap or fit under the seat. The carrier must be well-ventilated and secure to ensure the safety and comfort of the animal. Larger animals are usually not permitted unless they are service animals, which are protected under the Americans with Disabilities Act. It is advisable for pet owners to ensure that their pets are well-behaved and do not disturb other passengers during their journey. For additional details or any updates regarding the rules on bringing pets aboard, it is suggested to refer to the current web page of Chicago L.
