In America it does not belong to the rarities that railroad trains are attacked by bandits and are fired. Thus the persons responsible of the railroad management think to how the passengers would be to be protected in the carriages better. An idea is, the space are built between the steel records from those the walls of the railroad cars to fill with old phone books.

One has done the experience that the double steel walls, especially the rifle bullets, do not stand firm any more. In the space of the steel walls to accommodated phone books should offer thus a sufficient protection of the travellers. The road management asks the population for support and delivery of old phone books of the last years.
