The only way I can see the proposed extension working is to build a tunnel from Catford to FH station, possibly using the space on Perry Vale next to Forest Hill Cars as a station (with the platforms underneath, like Woolwich Arsenal DLR), which would connect with the current ELL station.

The map doesn't propose a station at the Old Fire Station end of Perry Vale which would be useful to connect Catford Bridge and Forest Hill stations as the bus service to those two stations are poor currently. This would also benefit the nearby schools on Mayow Road and relieve pressure from the 75 and 356 buses.

The other benefits could be to relieve pressure off the ELL and Southern services as passengers use the DLR to Canary Wharf instead of changing at Canada Water/London Bridge, it'd also connect us to Deptford and Greenwich for the first time without changing at London Bridge or using two buses.

However, I agree with Michael's proposal to extend the DLR to Bell Green instead, which would benefit one of the most deprived areas of the borough.
