The Tunnel Ratz steam to victory

This week the Tunnel Ratz, a team of London Underground engineers, took on Formula 1 engineers the Pit Stop Crew in a challenge to build a Railroad Racer.

The first round required the vehicles to change from road to rail and then race to the station. Round two requires the Rail racers to pull a heavy load up a gradient. Round three was all about speed, it was a straight dash to the chequered flag.

The Tunnel Ratz got off to a flying start, whereas the Pit Stop Crew had trouble lining their machine up on the rails. Round one to the Ratz. In round two the teams had to tow a trailer full of railway sleepers. The Pit Stop Crew posted a respectable time despite losing one of their guide wheels, but again the Ratz were quicker.

In round three, a straight dash, the Ratz again posted a quick time. It was all or nothing for the Pit Stop Crew, and they were going like a train! Then disaster: their machine derailed half-way down, signalling victory for the Ratz.
