Took some finding again, but the 10.23SX Pompey due 12.40 , empty to Streatham Hill, is shown as C.B.C.Yes I noticed that (and posted to that effect above) but ISTR they were Brighton and Eastbourne - didn't spot any Portsmouth/Bognor. But conceivable I missed them
Intriguing BTW is the use of a solo 4CEP on the overnight Gatwicks - presumably easier to do tickets than a BIL/HAL?
