We work with a smooth relative curve $X_U/U$ with nodal reduction over an
excellent and locally factorial scheme $S$. We show that blowing up a nodal
model of $X_U$ in the ideal sheaf of a section yields a new nodal model, and
describe how these models relate to each other. We construct a N\'eron model
for the Jacobian of $X_U$, and describe it locally on $S$ as a quotient of the
Picard space of a well-chosen nodal model. We provide a combinatorial criterion
for the N\'eron model to be separated.
