Tulip Olsen, voiced by Ashley Johnson, is the main character of Infinity Train Book One. Trapped on the mysterious train, she’s desperate to find a way back home, convinced that getting off is the only way to regain some sense of normalcy. Tulip is easily recognizable with her ginger hair, often pulled into a ponytail with bangs framing her face, and her trusty glasses. Throughout much of the series, she wears a casual, practical outfit—gray cropped leggings, a grey skirt, a green hoodie with brown elbow patches, and gray boots, always with a brown backpack in tow. By the end of her journey, Tulip’s appearance shifts to match her growth: she sports jeans, a burgundy hoodie, and a varsity jacket, reflecting a more confident, settled version of herself.
