RTA Rapid Transit has specific policies in place regarding pets on their trains. Generally, small pets that are contained in a carrier or bag that can be held in one's lap are allowed on the trains. This typically includes dogs and cats as long as they are secured and do not pose any inconvenience to other passengers. However, larger animals or pets that are not contained may not be permitted. It is essential for pet owners to ensure their animals are well-behaved and do not disrupt other passengers. For the most accurate and updated information regarding pets on RTA trains, it is advisable to refer to the official website, where all guidelines and policies can be found.
