Urban traffic contracts can now have routes of over an hour. However, there is only one piece of rolling stock per contract. Furthermore, it seems that trains are now each earmarked to a contract and another train cannot be used instead.
Even if the route in contract was 59min long, the train wouldn't have enough time to go back to a CY and back to a platform (I tried sending it straight back, but the number wasn't exactly the same, so it didn't work).
