SNCF Z 6400 6431Montgeroult-Courcelles Montgeroult-Cource..

The "disaster train" is the name of a train where future train drivers of Paris-Saint-Lazare region learn with a few monitors how to handle all emergencies such as emergency stops, stop on the line, used the security equipment...The tests are done on the Paris-Saint-Lazare > Gisors line J, because there is a low passenger traffic. The Z6400 never roll on this line except to make "disasters trains". So it's very rare to see a Z6400 here !
