On June 12, 2012, the International Agency for Research on Cancer (IARC), which is part of
the World Health Organization, announced that it has classified diesel exhaust as a Group 1
"agent carcinogenic to humans." What this means is that according to IARC, sufficient
evidence exists showing exposure to diesel exhaust gas causes cancer in humans - specifically
lung cancer, with a possible link to bladder cancer.

Many amusement train rides operating today around the world are powered by internal
combustion engines fueled by gasoline, propane, and diesel. The arrangement of the typical
train places these internal combustion engines in a locomotive shell at the lead of the train.
In most cases, the exhaust port is located so that it emits hot combustion exhaust out into
the air directly in front of the passengers, and sometimes directly in front of the ride
operator who can spend hours each day exposed to these exhaust emissions. Children and
the elderly, who often are the primary demographic found on amusement train rides, are
listed as most at risk to the effects of exposure to Group 1 carcinogens such as diesel
exhaust. If a train ride has a tunnel feature on its route, the exhaust exposure is
concentrated further into the breathing zone of everyone on the ride who passes through it.
One of the clear advantages of our battery-electric locomotives is that
they produce ZERO exhaust emissions. That not only removes the
objectionable smell of engine exhaust and fuel, but it eliminates the
health risk of exposure to locomotive exhaust gasses for passengers and
operators on or near the ride.
The result is a healthier environment, higher rider satisfaction and
significant reduction of the ride owner's liabilities to the general
public and their employees, which can additionally be used to
reduce the cost of insurance premiums.
