Is it an electric train with power lines above? They produce huge magnetic fields and will cause any compass to deviate.

Yep, if it were close to the power line, it might cause accuracy loss, but you can obviously easily find the compass accuracy in the top app bar, and if it goes 'very low', the alert dialog automatically popsup to notify you to recalibrate it.
