I use East Midlands Railway frequently and have never been on a train where everybody uses a mask. You got lucky travelling between Notts and Bedford. Trains, planes and automobiles definitely need masks to be worn, but will be impossible to enforce.
Unfortunately this highlights the problem with our mask, too expensive for a type IIR mask, not air tight enough to be classed as a FFP3 mask. It's a niche mask and the sales (or lack of) show this.
