Bogotá, 5.30 a.m.  

Isabela is waiting for the bus to go to work. 

Or rather, the first of three buses she needs to catch to get there. 

She's been doing this every morning, day in day out, for about a year and a half, because she really likes the job, even though it's tiring and demanding. 

She picks up her phone and sends a message: " Buen día, Abuelita!"

Her grandma Olympia has learned to read and write messages, since they don't see each other every day anymore. A few minutes later, she replies with a kiss (at 82, she's even learned to use emojis!), wishes her a good day and asks if they'll see each other today. 

Isabela looks up at the panel attached to the pole. She has a look at the bus panel and thinks about the new metro that's going to change the way people get around the Colombian capital. If she could choose, she'd call it “Linea Olympia” because it would allow her to visit her grandma every day without having to give up her commitments or her life, which she finally finds so fulfilling. 

Her friend Valentina has told her how she’s working on the new Bogotá metro project for an Italian engineering company that's part of the FS Group, and that they're supervising the project together with other international companies.  

Line 1 will be 24 kilometres long, running on an elevated track with 16 stations, connecting the south-west of the city to the centre. It'll be a cool and eco-friendly line that will totally change the urban landscape and give people time to spend together, just like Isabela and abuela Olympia.
