Note that RTT does not show a time in the GBTT^▸ (Great British Time Table) arrival/departure column, this means that technically those stops are operational and therefore are not advertised on Journey Planners.

If you look on journey planners for services from Ealing Broadway to Acton Main Line the only train to appear is the first Heathrow Connect service from Heathrow (which has a GBTT arrival time). For the other direction it is also just one service, the return working of the service previously mentioned! The same applied for the weekend just gone, not quite sure whether this was intentional or not.

Nor a Train Manager from what I have seen allocated, so 6.

RTT applies 'offsets' to the times provided by the train describer movement data. For arrivals these offsets are based on the time taken for a train to trigger the describer movement and come to a stand, and for departures the time taken for a train to trigger the describer movement after wheels start turning. Obviously there can be variation between different stock types, but unfortunately this is one of the limitations on reporting arrival/departure times in this way. Generally however RTT won't be hugely different to the actual time assuming the train gets a clear run into and out of the platform and isn't subject to any other issues such as wheel slip, etc, etc.

RTT has offset data for most of the country where train describer movement data is available, except in locations recently re-signalled where new data has to be collected. This is something that is on-going and hopefully will be available in the future.

1A03 stopped with a fault at the changeover point from Diesel to Electric, trains behind were diverted onto the Up Relief line Twyford to Slough. I presume the IET had carried on its journey (on diesel) by the time you got to where it had stopped (around Taplow).

Its not final yet anyway, its hard to tell how things will sound until you actually get it out there. There is some alterations being made over the next week to hopefully make it flow better. Volume is also being increased slightly.

Looks like two more diagrams from 13th November too.

Is it a welsh sounding lady? If so she is the new voice to feature on-board all GWR^▸ (Great Western Railway) trains.

Points were ran through at Gillingham. 1L26 was cautioned past a signal at red and the points at the Tisbury end of the loop were set incorrectly.

No, the four tracking ends at Filton Abbey Wood.

The work you mention sounds like it could be to do with the new Down Bristol Parkway Relief Line.

The current Stoke Gifford Siding which is currently at the end of the Down Goods Loop (Later known as the Down Bristol Parkway Passenger Loop) will be extended a short distance towards Filton and become the Down Bristol Parkway Relief.

This change allows a departure towards Filton from Platform 1 and a departure towards Wales from Platform 2/3/4 to leave Bristol Parkway simultaneously.

The line speed of the new platform line and the relief line is 50mph throughout. Platform 1 is likely to become the main platform for services towards Bristol from Westerleigh. Anything towards Wales has to use a 15mph crossover, similarly to avoid this everything will likely use the Down Bristol Parkway Relief.

That's just one of many ways a fail to call could present itself, although it'll be 'n/r' meaning No report. On this occasion it is more than likely the train was running under cautionary aspects and therefore because of the way arrival and departure times are reported it could easily look like the train stopped as normal.

It is Celia, however she has re-recorded everything and sounds quite different. It is an upgraded system SWT^▸ (South West Trains) have been slowly implementing, this is the latest addition however it is the first for a few months. It is at a number of other stations including Eastleigh, Winchester and Southampton Airport Parkway. It does seem to be a bit unreliable mind.

Most likely run-round in Jersey sidings.

This is the timing load of the train from origin. It is likely it changes somewhere before going on the branch. Therefore it most likely changes somewhere for 55mph on the way down, and change somewhere for 95mph on the way back.

It looks like the train paths have changed too, only by a minute or so on the way to Weymouth, significantly on the way back though. I feel sorry for anyone who wanted to connect onto the 2030 CrossCountry service back North, as its highly likely they'll miss it as a result of the change. The return working now arrives at Bristol TM^‡(resolve) at 2029, it was previously advertised at 2009 arrival.

Nope
