Will the temperature in the magic dining car rise after summer exposure?

No, my cousin bought a magical shop car, and I went to help her sell ice cream at noon last week. This car is not hot at all. According to my cousin, the magic shop car has three layers of heat insulation design, which is waterproof, heat insulation and cold-resistant. The carriage is made of all stainless steel, and all the glass is toughened and glued to ensure that it will not feel hot even at the high temperature of 38 degrees.
