Railroads could have key role in combating pandemic
Perhaps the biggest difficulty of distributing this particular vaccine is that it must be stored at negative 80 degrees Celsius, requiring special dry-ice containers. Pfizer says it has developed a dry-ice box that can maintain an internal temperature of around minus-70 degrees Celsius for up to seven days. But refrigerated railcars might extend that longevity and make it easier to get the vaccine to parts of the country that don’t have stationary cold storage capability or the kind of facilities necessary to vaccinate large numbers of people.
