Four people were killed and 16 were injured Thursday night after a train struck a Show of Support parade float en route to banquet at the Horseshoe. 
  
 Two people were killed at the scene; two died at Midland Memorial Hospital. One victim was transported to Lubbock, and several others were released from Midland Memorial late Thursday evening, said Chief Price Robinson, of the Midland Police Department. Marcy Madrid, a Midland Memorial spokesperson, told the Reporter-Telegram late Thursday that of the 16 injured admitted to Midland Memorial, 10 were treated and released, four were in stable condition, one was in critical condition and the other was transported to Lubbock. The victims’ names were not released. 
  
 A float carrying veterans and their spouses in the ninth annual Show of Support parade was struck by an eastbound train about 4:36 p.m. near the corner of Garfield Street and Industrial Avenue, Robinson said. 
  
 The parade was taking 24 veterans and their spouses from the DoubleTree by Hilton to the Horseshoe in south Midland. 
  
 According to officials, the trailer hit was the second of two carrying veterans near the end of the parade route. The first trailer already had crossed the train tracks. 
  
 The trailer was carrying 26 passengers — 12 veterans, 12 spouses and two civilian escorts — Robinson said. 
  
 Midland County Sheriff Gary Painter said the trailer was almost across the tracks when the train struck it. 
  
 “It was pandemonium at the point of impact. Some (of the veterans) tried to jump and protect each other, their girlfriends and their wives,” he said. 
  
 Authorities at the scene were going through the roster at 6 p.m. to account for everyone involved. 
  
 In 2003, the speed limit for trains traveling through Midland increased from 40 to 60 miles per hour. 
  
 Officials with Union Pacific at the time said speed increases bring effectiveness to motorists who don’t have to wait at railroad crossings as long, while helping trains move along faster and more efficiently. 
  
 Union Pacific spokesman Tom Lange said the eastbound train was sounding its horn before it hit the float Thursday as it approached the railroad crossing. He said the crossing gate and lights were working at the time. 
  
 Lange didn’t know if the train crew saw the float approaching. 
  
 Officials would not comment on if the driver will face any charges or what caused the wreck, saying the crash was still under investigation. The Associated Press reported that the National Transportation Safety Board is in charge of the investigation, but Robinson said at a press conference Thursday night that MPD was investigating the wreck. 
  
 Painter, a veteran himself, said that Midland suffered a severe tragedy Thursday. 
  
 “I am very hurt and very shocked. My emotions are running pretty high,” he said. “Our feelings and thoughts are going out to all the people.” 
  
 Show of Support officials scrambled to find private transportation for wounded individuals and their families who were not from Midland. Directors said they planned to establish an account at Western National Bank to provide for the families’ needs. 
  
 The parade was supposed to lead up to the Hunt for Heroes banquet. Wounded servicemen were supposed to be treated to an all-expenses paid white tail deer hunting trip this weekend, and their spouses would be treated to a variety of activities in Midland. 
  
 All Show of Support events have been canceled, said Terry Johnson, the organization’s president and founder. 
  
 Earlier that day, the servicemen were treated to a luncheon at the Commemorative Air Force. State Sen. Kel Seliger and Mayor Wes Perry spoke at the luncheon. 
  
 “I’m just sick; I’m sick to my stomach,” said Perry, who gave each man a key to the city at the luncheon. “They’re heroes; they’re the best of the best. I was honored to be in their presence.” 
  
 Clergy and other volunteers arrived at the DoubleTree, where the families were staying, late into the night to provide support after the accident. Many said they had heard the news and stopped by to see if they could be of assistance. 
  
 “I wouldn’t expect Midland to act any other way,” said Donny McClure, a Show of Support director. “This is a time when the entire community, state and country comes together to pray for families who are in need beyond description.” ||||| A freight train slammed into a parade float carrying wounded veterans on Thursday, killing four people and injuring 17 others as the float tried to get through a West Texas railroad crossing on its way to an honorary banquet, authorities said.

 The train was sounding its horn and people were jumping off the decorated flatbed truck before the collision around 4:40 p.m. in Midland, according to witnesses and Union Pacific spokesman Tom Lange. A preliminary investigation indicates the crossing gate and lights were working, Lange said, though he didn't know if the train crew saw the float approaching. 
  
 Two people died at the scene, while two others died at Midland Memorial Hospital, City of Midland spokesman Ryan Stout said. Six people remained hospitalized Thursday night, including at least one in critical condition; the other 11 people injured have been treated and released, hospital officials said. 
  
 About two dozen veterans and their spouses had been sitting in chairs on the float, set up on the back of a flatbed tractor-trailer decorated with American flags and signs identifying each veteran. Many seemed to panic as the locomotive's horn sounded, said Patricia Howle, who was waiting in her car at a nearby traffic light as the train approached. 
  
 "I was on the phone, and I just started screaming," she told The Associated Press late Thursday night. "The truck was on the other side of the train, but I did see the panic on the faces of the people and saw some of them jump off." 
  
 The float was among two flatbed tractor-trailers carrying veterans and their spouses. Police said the first truck safely crossed the railroad tracks, but the second truck's trailer was still on the crossing as the train approached. 
  
 "The train honked its horn, but the 18-wheeler could not go anywhere because of the other one being right in front of it," said Daniel Quinonez, who was in traffic that had been stopped by sheriff's deputies to allow the parade to pass. 
  
 "It was a horrible accident to watch happen right in front of me. I just saw the people on the semi-truck's trailer panic, and many started to jump off the trailer. But it was too late for many of them because the train impacted the trailer so fast," he told the AP. 
  
 Several police vehicles remained at the crash scene late Thursday night. Flood lights illuminated the wreck as investigators in reflective vests and hard hats carefully took measurements of the site, which was cordoned off by yellow police tape. 
  
 The parade had been scheduled to end at a "Hunt for Heroes" banquet honoring the veterans. The wounded service members were then going to be treated to a deer-hunting trip this weekend. The events were canceled. 
  
 The events were organized by Show Of Support, a local veterans group. Its president, Terry Johnson, did not immediately return an email for comment and his phone number was unlisted; the phone rang unanswered at the group's offices. 
  
 Stout, also the police department's spokesman, said he had no information about the individuals who died or the driver of the truck. 
  
 Lange said Union Pacific is offering help to the community and victims' families, as well as peer-to-peer counseling for the train crew, who did not sustain any injuries. 
  
 "There is going to be a very thorough investigation," Lange said. "It's obviously a very tragic incident." 
  
 The National Transportation Safety Board also is investigating, NTSB spokesman Peter Knudson said. 
  
 Secretary of Defense Leon Panetta "was deeply saddened by news of the tragic accident involving veterans heroes and their spouses in Midland," Pentagon spokesman George Little said in a statement. "His thoughts and prayers are with the families of the victims, with those injured in this incident, and with the entire community." 
  
 Midland is about 320 miles west of Dallas.

Output:
A freight train crashed into a wounded veterans' parade float in west Texas yesterday, killing four people and wounding 17. At least one of the wounded is still in critical condition; 11 have been released from the hospital, officials say. The float had been carrying 25 people—mainly veterans and their spouses—from a hotel to a banquet, the Midland Reporter-Telegram reports. It was hit as it crossed train tracks, though the crossing gate and lights were working, according to an initial investigation. Two trucks were carrying veterans, and one made it across the tracks safely before the other was hit. "The train honked its horn, but the 18-wheeler could not go anywhere because of the other one being right in front of it," a nearby driver tells the AP. Says a local sheriff: "It was pandemonium at the point of impact. Some (of the veterans) tried to jump and protect each other, their girlfriends and their wives."
