Derails are already installed in tracks where cars are left for extended periods of time (several days or even weeks). A portable derail is only good when there is someone present all the time to make sure nobody removes it.
When there are enough handbrakes, the cars will not move, irregardless of heavy winds or grade.

Next time I am at a railway siding that has derailers installed I will take a closer look at them. I just thought that they are easy to install. I did notice that there is a lock on them. Can they be unlocked and then flipped over and out of service to allow a train by and then flipped back into service again and relocked?
