When I'm playing german routes, I'd love to have the option to just display permanent speed restrictions on the HUD as they get lost within the junction speed limits.
Juction speed limits are permanent speed restritions. The HUD only displays line speeds, even if it's just a short section of railway line. (The junction itself). The HUD completely ignores speed restrictions given by signals, which is a shame, as signals usually warn you of upcoming speed changes way before the HUD does.
