Abstract
We obtain the strong approximation of the sojourn time progress for a two-stage tandem queue in heavy traffic, that is, the traffic intensity \rho_1=\rho_2=1. The sojourn time is the period from a customer's arrival to her departure, and the strong approximation is a function of Brownian motion.
