Group 2: Consumer Behavior and Pricing - High-speed train meals, particularly boxed lunches, are priced between 15 to 80 yuan, making instant noodles a more economical option for travelers [2]. - The price of instant noodle alternatives at East Station is around 12 yuan, slightly higher than typical instant noodle prices, indicating a shift in consumer preferences [2]. Group 3: Service Quality and Market Response - The railway department's management of instant noodles is currently a "soft guidance" approach, as there is no outright ban on passengers bringing and consuming instant noodles on trains [2]. - Enhancing service quality could involve increasing the supply of affordable meal options at stations and on trains, rather than solely eliminating instant noodles [2].
