This is a passenger announcement. You can now book your train on Uber and get 10% back in credits to spend on Uber eats.

So you can order your own fries instead of eating everyone else's.

Trains, now on Uber. T's weekly podcast on the market, the economy and the world of business.

Welcome both of you.
