Speed indicator

Eurotunnel train drivers have their maximum speed dictated by operators in the railway control center, either on the UK side of the tunnel or the France side. Generally, non-Eurostar trains have a maximum speed of 140 kilometers--87 miles--an hour. Eurostar trains are allowed to travel up to 160 kilometers--99 miles--an hour. Here, we see that Tracy's train is going 138 kilometers--86 miles--an hour.
