We give a TDI description for a class of polytopes, which corresponds to a restricted 2-matching problem. The perfect matching polytope, triangle-free perfect 2-matching polytope and relaxations of the travelling salesman polytope are members of this class. The paper shows that 2-matching problems for which the unweighted problem was known to be tractable, the weighted is also tractable.
