Narrow Margin (1990)
Gene Hackman spends most of the films runtime on a train protecting a witness (Anne Archer) from the Mafia bad guys trying to kill them and stop her testifying against their boss.
For me the film is bookended by two impressive stunt sequences that can't mask the dull, (a lots of time walking up and down train carriages) but ludicrous and predictable events that happen while they are all on the train.
There's so much time spent going up and down the train, for no reason, that it's almost like they only had a hours worth of film script and had to drag it out to 90 minutes.
