The blue mail icon would serve the same purpose as the XP Wagon icon. It denotes a mail wagon rather than the capacity some thing has to hold mail. It also make more sense when used in conjunction with dual use since that is a blue person and a blue envelope.

Think of it in the use of the info box. The blue envelope or person would be in the upper right corner while the or  icon would be in the body of the info box with a number to denote how many. Similar to how they are used in the game. In the case of a train set, the blue icons could still be used since we are mainly identify the wagons and not the amount a wagon could carry.

Now, on to answering the other thread. . . . . ..
