Getting Around

I took a different train today
From what I often take.
I had an errand leading me –
It wasn’t a mistake.

I’d checked the map and learned the route;
It wasn’t hard to do.
In fact, it felt familiar,
Seemed like something I once knew.

So now I have another way
To travel ‘round the city.
Sticking to the same old path
Some folks would think a pity.

There still are subway lines to which
I am a total stranger.
What’s prevented me is much more
Circumstance than danger.

Perhaps one day, I’ll need to use
A new train on the map.
I’ll add it to my repertoire,
A feather in my cap.
