One group's excitement over their trip on the Napa Valley wine train turned into a big controversy after they were kicked off the popular tourist attraction for being noisy.

Members of a book club say they purchased tickets months ago to enjoy the 25-mile route, which travels through the beautiful wine country while passengers eat and drink wine. However, the 11 book lovers say that they were humiliated when they were asked to leave on Saturday for being too loud. The members of the book club, which consists of 10 black women and 1 white woman between the ages of 39 to 85, also believe they were kicked off the wine train because of their race.

According to Lisa Renee Johnson, the leader of the "Sistahs on the Reading Edge," the train's maitre d'hotel asked the women to "keep it down" before they had left the station, reports the San Jose Mercury News. She then asked again after the women laughed in unison when another passenger cracked a joke.

"We told them that when we laugh at the same time, it's difficult to keep it quiet because that's the nature of groups of our size," said Johnson, adding that there seats were scattered throughout the car, which made it harder for them to have a conversation.

"Noise is going to come along with that, and laughter, because it's fun! It's wine and not just a glass of wine, it's free-flowing wine," she told KTVU.

Once another passenger complained, the train's maitre d'hotel escorted the ladies through six train cars before exiting at the St. Helena station, where police were waiting.

"It was the most humiliating and embarrassing experience I've ever had," said Johnson, an Antioch author who has organized the group's annual Napa day trips for the past 17 years.

"Why didn't they just move that party to a different car, rather than make all of us get off the train?" wondered book club member Linda Carlson.

"It was very humiliating, very degrading, and it made my mom cry, which made me cry," added member Dininne Neal.

"Our servers didn't feel we were loud and obnoxious," insisted club member Debbie Reynolds, "they felt we were just laughing."

Wine Train Spokeswoman Kira Devitt released a written statement, stating that it is standard policy to remove guests who are disruptive.

"We do not enjoy asking guests to depart early, but we take these issues seriously to ensure the safety and enjoyment of all of our guests, the statement reads.

The Wine Train Facebook page accused the group of "verbal and physical abuse." However, the post has since been deleted. Following the incident, the train company's president, Tony Giaccio, apologized to the group.
