This has come up more generally in the past but not sure if this specific example has come up.
What is the reason why the Monday to Friday 17:45 Portsmouth Harbour to London Waterloo cannot stop at Clapham Junction. It passes there at 19:22 and the next service appears to be the 19:29 Basingstoke service which also passes through. 7 minutes is long enough between services, given the Exeter to London Waterloo train stops at 19:40-41 and Weymouth to London Waterloo services passes through at 19:44, just 3 minutes later.
As the time the train gets to Clapham Junction doesn't appear to be the issue, is it due to needing to be at London Waterloo by a certain time or it will block trains departing London Waterloo? It arrives into London Waterloo at 19:29 and then departs again as the 20:05 to Bournemouth but I appreciate there are other trains departing London Waterloo besides this one and there might be a conflict of moments.
