In all accounts of Einstein’s train-lightening thought experiment the ground observer sees the two flashes simultaneously because he remains “at rest” with respect to the landscape, while the train passenger sees the forward flash first because she is “moving” toward the location where it occurred. However the only motion here is the relative motion between the train and the landscape as they slide past one another.
Our Earthly experience leads us to consider the ground to be “at rest”, while trains “move”. But relativity says this isn’t so. We are just as free to consider the train “at rest” while the landscape rushes by.
In this scenario the train passenger remains “at rest” midway between the two strike locations and therefore sees the strikes as simultaneous. The ground observer, rushing toward the train’s rear, sees the rear strike as occurring first for the same reason the original scenario has the passenger see the forward strike first.
Thus, both observers see the strikes as simultaneous. Their mistake is in assuming that the other observer sees them as sequential. But this is non-relativistic thinking.
I have relied on the exact same reasoning as does the original explanation. The “resting” observer sees the flashes simultaneously while the “moving” observer sees the closer flash first.
I submit that my description is the only one which employs true relativity while the others employ absolute motion and rest.
