First Tube Puzzle Of 2020

I MISSED out on public transport during the lockdown and I have had precious few reasons - no league chess to go to, for instance - for using it since.
But recently I saw the following serial number on a Northern Line train: 51578.
As usual, each number should be used once, and once only, and must be added, subtracted, multiplied or divided to make a balanced equation.
