Let Y be a curve over a p-adic number field K. We discuss an algorithm for computing the Weil-Deligne representation of Y from its stable reduction to characteristic p>0. Of particular interest are the cases of superelliptic and plane curves, where it is known how to compute the stable reduction. This is joint work with Bruno, Do, Wewers, and Zhang.
