Take the #7 train, it might be fun. ] 'Wright' boards train to last Shea opener By Bill Hutchinson Daily News Staff Writer Tuesday, April 8th 2008, 4:00 AM If you spot Mets star David Wright on the No. 7 train Tuesday, don't mistake his waxy look for Opening Day jitters at Shea. To celebrate the last opening at the 44-year-old Queens ballpark, a wax figure of the Amazin's third baseman will ride the train from the 42nd St. station to the game. The life-size replica will leave Madame Tussauds Wax Museum in Times Square for the first time since being unveiled last year to commemorate Shea's final season. Weather watchers are forecasting balmy temperatures for today's 1:10 p.m. first pitch against the Philadelphia Phillies. It won't be hot enough to cause Wright a meltdown, said meteorologist Mike Silva of the National Weather Service. He said morning clouds will give way to sunshine with temperatures in the mid-50s. The Metropolitan Transportation Authority is rolling out its "nostalgia train" to ferry the waxy Wright and other dignitaries, including Mr. Met. The train will feature an original "Bluebird" car, the type that ran on the 7 line when Shea opened in 1964. Mets officials are to board the train with the Wright statue at 11:30 a.m. and help the MTA pitch its "Take the Train to the Game" initiative at a noon press conference at the Willets Point/Shea Stadium stop.
