A question which has no doubt been asked before, if so - sorry, St James's Park is currently closed but trains proceeding through slow down to walking pace, for a moment or two, and then accelerate away again. I haven't seen anybody working on the platforms during my mid-day transits and therefore wonder the reason for doing this? Anyone able to satisfy my curiosity, thanks, Richard M.

St. James's Park reopened on Sunday, now 0700-2300 each day after being closed 22 March, one of the 40ish to do so. Procedure for passing closed stations is 5mph passing the station starter at clear. |

5mph through closed stations are the norm on conventionally signalled lines for a variety of reasons including protecting workers, accommodating timed occupancy signals without stopping and keeping to the timetable with the latter perhaps being most pertinent to St James's Park.
I'm fairly sure that [sic] Thales TBTC lines are 12 mph non-stopping stations [sic] as is the Central line.

Station starters generally have shorter overlaps (safe breaking distances).

I'm fairly sure that Thales ATO lines are 12 mph non-stopping stations whilst the Central I think is closer to 5 mph. 92's maintain 20kph through skipped stations |

Just to be clear, there’s no speed restriction through a closed station, but it’s 5mph as cab passes starter. There are exceptions such as Ravenscourt Park, Stamford Brook, Turnham Green and Chiswick Park where the PSR is signed.

Met Main Line has longer overlaps on the starters so trains can non-stop at line speed as do the Netowrk Rail bits of the District, Gunnersbury-Richmond and East Putney-Wimbledon.
