Number 7 - International Train
It’s 8.15 in the morning and Manuela Garcia is on her way to college in New York City. She is sitting on the Number 7 train and doing her homework. Chinese women are sitting next to her, they are chatting in Chinese. An old woman gets on the train; she is wearing a sari and reading a book in Hindu. At Jackson Heights the old woman gets off. It’s raining outside and Manuela can see Indian and Pakistani shops in the street below.
Welcome to the International Express, the most international train journey in the world. Every day some of New York’s three million immigrants take Number 7 train from Queens to Manhattan and each stop is like a different country. Get off at Flushing station and experience China, go to Corona and you’re in Mexico, the next stop is India at Jackson Heights. Many people are from Latin America, Eastern Europe, Africa or Asia. If you listen carefully, you can hear more than 100 different languages.
Why is this train so popular? A hundred years ago, most immigrants lived i
Manhatten, but in 1910 Manhattan was overcrowded and life was very difficult. Then in1917, things improved, thanks to a new train to suburbs called Queens. Immigrants moved out of the city because there was more space in Queens, but they could still get to work in Manhatten.
These first immigrants came to New York to escape from poverty and war, and to have a better life. Today, people come for the same reasons. Manuela Garcia’s family is typical. Her father, Tomas, came from Mexico in 1986 and sold tacos from a small food stall next to Corona station. Tomas got through hard times, saved his money and bought a bakery. Today the jukebox there plays Mexican songs and satellite TV shows Mexican TV programs. “We are proud of our culture, but the bakery is not just for Mexicans”, says Tomas. “We have Polish and Turkish customers, too. We all get on with each other.”
The train speeds past LaGuardia airport as the rain stops and the sun comes out. Manuela looks out of the window and watches the planes take off. People are getting away to experience the world. Manuela smiles. She doesn’t need to go to faraway countries - the world is right there on the Number 7 train.
