Snakes on a plane? Maybe not. But pets on a train? Perhaps.

Rep. Jeff Denham (R-Calif.) introduced a bill Tuesday that would allow travelers to be able to take their dogs and cats on certain Amtrak trains.

“My dog, Lily, is a part of our family and travels with us to and from California all the time. If I can take her on a plane, why can’t I travel with her on Amtrak, too?” Denham said in a news release announcing the legislation. “Allowing families to bring their animals with them will facilitate transportation and efficiency while also providing a much-needed source of revenue for Amtrak.”

Current Amtrak policy doesn’t allow pets with the exception of service animals.

H.R. 2066, The Pets on Trains Act, is co-sponsored by Rep. Steve Cohen (D-Tenn.). It has been endorsed by the Humane Society of the United States. The legislation would require Amtrak to implement a pet policy.
