Wear Comfortable Clothing For the most enjoyable experience, especially during a long-distance journey, you'll want to wear clothing that is super comfortable, along with warm socks. Oftentimes, the train cars can get cold, even if you're not seated by the doors that connect the cars together.

There is no formal dress code for Amtrak, so most people prioritize comfort and layers. In 2026, the standard "train uniform" consists of athleisure or casual wear, such as leggings, joggers, t-shirts, and hoodies. Because train cars are often kept at a very cool temperature by the AC, even in summer, bringing a light jacket or a pashmina is highly recommended. For long-distance overnight trips in Coach class, many passengers bring a small blanket or wear a "travel set" that feels like pajamas but looks like loungewear. If you are traveling in a Sleeper Car (Roomette or Bedroom) and plan to dine in the Dining Car, you might see people in "smart-casual" attire (like a polo shirt or a sundress), but even there, jeans and clean sneakers are perfectly acceptable. The only strict rule is that you must wear shoes at all times when walking through the train, including moving between cars or going to the cafe car. Slip-on shoes or comfortable sneakers are the preferred choice for most experienced rail travelers.
