Check baggage BICYCLE policy EB train:
Bringing Your Bicycle
Carry-On/Trainside: Bicycles and folding scooters up to 50 lbs. Standard bicycle sizes apply. Maximum tire width: 2"
Checked: Bicycles up to 50 lbs. and 70" x 41" x 8.5" and non-folding scooters
Carry-On Bicycle Service
Standard full-size bicycles may be carried onboard and stored within the body of the car. On short-distance routes in the Northeast, passengers must remove the front wheel before storing their bike. Fee varies by route. Beginning January 1, 2024, lithium-ion powered foldable scooters and e-bikes are also accepted as carry-on items.
Specially Designated Spaces Only
Bicycles must be stored in the designated racks/areas inside Coach passenger cars. On trains with unreserved carry-on bicycle service, racks are available on a first-come, first-serve basis. When the racks are full, bikes will no longer be accepted onboard. Scooters can be stored wherever foldable bikes are permitted.
Loading and Securing Your Bike
Passengers must be able to fully handle their bicycle or scooter in order to carry it on the train and stow it in the designated area or rack. Passengers are responsible for supplying their own cords and locking devices into their most compact position prior to boarding. All large seat/saddlebags, handlebar bags, baskets and panniers must be removed from your vehicle, consolidated and either checked or carried with you onto the train.
Exceptions on California Routes
San Joaquins and Capitol Corridor routes will accept vehicles with a 2.5" maximum tire width; the Pacific Surfliner will accept a 4" maximum.
Non-folding scooters can only be stored in designated train cars with a bike logo and must be secured parallel or adjacent to the bike racks. They cannot block any aisles or walkways, impede passenger movement or present a safety hazard. If a non-folding scooter cannot meet these conditions it will need to be checked in a baggage car.
Liability
Amtrak disclaims liability for loss of or damage to bicycles carried onboard and stored in bike racks or any other recreational vehicle brought onboard.
Folding Bikes Brought Aboard as Carry-On Baggage
Folding bicycles smaller than 34" x 15" x 48" (860 x 380 x 1120 mm) and scooters under 50 lbs. are allowed onboard all trains in lieu of a piece of carry-on baggage.
Only certain passenger cars can accommodate folding bicycles as carry-on baggage, otherwise they must be checked.
Only true folding bicycles (bicycles specifically designed to fold up into a compact assembly) are acceptable. Generally, these bikes have frame latches allowing the frame to be collapsed, and small wheels. Regular bikes of any size, with or without wheels, are not considered folding bikes, and may not be stored as folding bikes aboard trains.
You must fold down your folding bicycle or scooter before boarding the train. You may store the bike only in luggage storage areas at the end of the car (on the lower level of Superliner trains). Folding bikes cannot be stored in overhead racks. Scooters can be stored wherever foldable bikes are permitted, under the seat or between the passenger's legs. Non-folding scooters must be checked.
Trainside Checked Bicycle Service
Standard full-size bicycles may be transported in bicycle racks located in the baggage car. Passengers are not allowed in baggage cars; Amtrak personnel will store and secure your bike in the bike racks. Before handing your bicycle to an Amtrak crew member, please remove any large seat/saddlebags, handlebar bags or panniers. These items must be consolidated and either checked or carried with you onto the train. This service is only available at select stations.
Boxed Bicycles in Checked Baggage
Bicycles may be checked on Amtrak between all cities where checked baggage is offered. Not all trains or locations are equipped to handle checked baggage. Find your station(s) to see if this service is available.
Bicycles/bicycle trailers may be checked in a bicycle container for $10, in lieu of a piece of baggage. Bicycle boxes are sold at most staffed locations for $15 per box. Customers may supply their own bicycle container.
Recumbent, tandem and special bicycles over the standard bicycle dimensions and will not fit in a standard bicycle box are prohibited. Motorized bicycles are prohibited.
The fee for checking a bike as baggage is $10.00. This is subject to change without notice.
