Welcome to the fire newguy. I would definatly add a small NOAA hazards alert radio with S.A.M.E. technology. This will alert you if something does occur. Walmart has pocket-sized ones for about $40.

How far away are you from secondary sanctuaraies such as your parent's, relatives, friends, or friend's homes? Do you have good maps of the areas and directions to reach these places?

As for identifying what hazardous materials the trains are carrying, go here. You can order an emergency response book which lists the chemical every hazmat placard ID number refers to as well as software for your pc or pda which gives you the same information. I keep a copy of this book in my glove compartment.
