Hi, delvillardennis!
Thank you for your kind words and glad to hear you liked it, ask me if you got stuck with something.
But there's no need to dig up so deep your Spanish dictionary as:
a) worksheet "Instrucciones" (Instructions) is both in Spanish and English
b) worksheet "Estaciones" (Stations), just 10 column headers (2 groups of 2 by 2 options + 2)
c) worksheet "Horarios" (Schedule), just 5 column headers, all the rest are station names
d) worksheet "Parametros" (Parameters), 4 column headers, 8 values and 8 descriptions
e) worksheet "Diagrama" (Diagram), nothing at all
f) VBA project uses English, ok, the names, not any problem if done all previous
Regards!
