Southbound services from Forest Hill on Saturday and Monday terminate at Coulsdon Town but on Sunday terminate at Caterham/Tattenham Corner or Crystal Palace.
Hopefully this work will be finished on time this weekend and we have a two week respite before more engineering work starts on September 19th closing the line to and from New Cross Gate for 4 weekends. This will result in no trains at all and therefore bus replacement services!
