Let C/K be a curve over a local field. We study the natural semilinear action
of Galois on the minimal regular model of C over a field F where it becomes
semistable. This allows us to describe the Galois action on the l-adic Tate
module of the Jacobian of C/K in terms of the special fibre of this model over
F.Comment: 13 pages, final version, to appear in Proc. AM
