From NetFlix:

When a mother commits suicide by parking her car on the train
tracks, an unlikely bond forms between her son Davey (Miles
Heizer) — who’s wracked with guilt — and the tormented
engineer (Kevin Bacon) who was driving the train that fateful
day. Oscar winner Marcia Gay Harden co-stars as the engineer’s
wife in the directorial debut of Alison Eastwood (Clint’s
daughter).

I can’t remember if I have ever seen Kevin Bacon or Marcia Gay Harden in a bad film. “Rails & Ties” is a sad feel-good. It offers universal human values. The son Davey could have been a bit better. Sometimes the film seems to solve problems too easily. I think adolescents could watch this despite a sad scene in which Marcia Gay Harden inspects her breasts (one already disfigured by a cancer operation). The less hard-hearted of you might even shed a few tears.
