I noticed today when collecting materials from trains at friends stations that the first box was coloured brown, and had the word museum on it along with a number.

Does anyone know what this is for, as I didn't actually add any new engines to my museum???. And the number in the box was different at each friend I collected materials from, I think the highest number was 10.
