Reversing a near decade-long ban, Amtrak will allow passengers to bring guns on most trains starting next month. The change, pushed by gun-rights advocates and ordered by Congress, aligns Amtrak’s firearm policy with air travel rules that allow unloaded guns to be stored in locked baggage holds. Federal Homeland Security officials on Monday said they are OK with guns being on trains as long as security protocols are enforced. "It’s deemed safe and appropriate," federal Transportation Security Administration spokesman Nico Melendez said. "If people follow the rules, it’s pretty simple."
