Since return address is stored in inventory of the heading cart of trains, care must be taken to avoid modifying the inventory. Use specific material to write address to avoid unwanted change. Usage of BC7021 sign to separate the train head of the wagons before performing inventory operations is a good practice. Usage of book tickets is another solution.
