The Top 8 duos are halfway through the competition and the challenges are getting tougher by the week. Today, the duos face another intimidating team challenge outside of the MasterChef kitchen. This time, two teams must prepare a VIP dining experience aboard a moving steam train. It's a race against the clock and an intense test of the duo's teamwork, to see which partners can keep from running off the rails. The team with the fewest votes from the diners will face elimination in the dreaded Pressure Test.
