As well as attracting international attention, the Nostalgia Lunches also proved a stimulant to the domestic market. Major chains like 7-Eleven, Family Mart, Hilife, and Circle-K put out their own variations on the boxed lunches, and now everyone wants a piece of the action. Even buffet restaurants are hanging "Railway Lunch" banners over their doors, trying to jump on the bandwagon.
不僅如此，自從鐵路懷舊便當上市後，大大刺激了國內便當的消費市場，包括統一、全家、萊爾富、0K 等超商紛紛推出各自研發的便當，大家不約而同來爭奪這塊大餅；甚至一般自助餐廳也打鐵趁熱，在門口高高掛起「鐵路便當」的布條，企圖吸引食客光顧。
