Okay, so if I go to Appearance – Editor – Styles – Typography – Fonts – Install Fonts, I can individually install a Google font. It appeared that the font that I was looking for was spelled Raleway, and not Railway. I found it and installed it. So it is possible for me to install individual Google fonts, which is already great.
I guess this is sufficient for me 🙂
Ah yes, I am using Spectra Version 2.19.7.
