The Flying Scotsman could be banned from main line tracks after people trespassed to catch a glimpse of it.
There was chaos between Derby and Birmingham last Sunday as fans vied to spot the legendary loco on its UK tour.
The situation was blamed for a string of delays to normal services, with reports of people refusing to move when challenged by drivers.
Network Rail said a ban would be a "move of last resort" but could not be ruled out if lives were being risked.
It would not let "a few thoughtless lawbreakers" cause dangers and delays, it said.
