Do trains have speed limits?
Yes they have to follow a certain speed limit while they are
going through a town,city,or even a suburb.
* Added - In the US, for every train line and for every train
there are speed limits both imposed by regulation and by railroad
rules. By Federal regulation, trains are limited to certain speeds
based upon the condition of the track and how often it is
inspected. In addition, depending upon the type of train and the
particular locomotives and cars in the train, Federal regulations
and railroad rules impose speed limits. The most restrictive speed
limit, meaning the slowest, that applies to the train is the speed
limit the train must obey. Additional speed limits that reduce the
speed further may be imposed temporarily or permanently for many
reasons.
