Opening new lines, like building new roads, might hurt everything due to induced demand.
You can reduce demand by not needing everyone to go the same place every day. Why does everyone have to work in London and why don't they already live where they work?
Induced demand means people are now able to practically get places when they couldn't before. It doesn't mean "hurt everything."
And more people moving more places means more growth, probably. If everyone stayed at home not much would get done.
