As part of the redevelopment of London Bridge, Forest Hill was suppose to get an additional 2 trains per hour from London Bridge.
However, given this year's congestion at LB I wouldn't be surprised if they are just going to give up on it and let the ELL take the capacity past New Cross Gate.
New Cross? They are better off setting up 2 free shuttle buses from New Cross to New Cross Gate. Given the total over subscription of the FH route, they need to change it regardless. The initial set up just isn't warranted anymore.
