Note you don't have to say the same exact sentences. Alexa is smart enough to parse your sentence into commands that she understands with this skill and reply to you with information you ask. She will also ask to clarify if she needs more information such as the line color and the station name.
You can say "Alexa ask metro status for next silver line train at Metro Center station".
- Arrival times of the next trains to each destination: Since a metro line is bi-directional and sometimes it stops at different destinations, Alexa will list out the trains to each destination for you.
- Subsequent arrival times after the next train: In case you can not make it to the very next train, Alexa will list out the subsequent trains' arrival times as well.
You can either invoke the skill about saying "open metro status" or just directly ask Alexa a question by saying things like "Alexa ask metro status for next silver line train at metro center?"
