A train carrying Republican members of Congress, including Montana Sen. Steve Daines and Congressman Greg Gianforte, to a retreat in Greenbrier, West Virginia, hit a truck on Wednesday morning.

Q2 reports that the lawmakers were scheduled to spend the next few days at the West Virginia resort for their annual issues conference. Neither Gianforte nor Daines were injured. Sen. Daines tweeted from the train that he’s okay, but called for prayers for the driver of the truck.

The specially chartered Amtrak train departed Union Station in Washington, D.C. at about 8:30 a.m., and hit the back of a garbage truck at about 11:20 a.m. in Crozet, Virginia. The impact reportedly threw several train passengers from their seats, but so far, none of the lawmakers appear to have sustained major injuries. Many were also traveling with their spouses and staff.
