I notice today that some tfl rail trains are skipping maryland, but this is the only station they skip on route to Brentwood, is there any reason for this?

On their twitter there's two different sets of stations being skipped for overrunning engineering works. Maybe Maryland is the last to reopen. twitter.com/TfLRail |

Every other train IS stopping at maryland which is why I'm wondering why half are not

It's standard for Sunday. The half-hourly Shenfield stoppers call at all stations. The Gidea Park shuttles (also half hourly) for some reason omit Maryland and have done for years. There appears to be no rhyme or reason either as once or twice where there has been a 15-min Shenfield service when engineering works have been occurring, Maryland was served by all trains. Go figure.

my only guess could be that maryland is not seen as requiring any more than a 30 min service on these days and helps customers from stratford/Liverpool street reach further destinations a little quicker. Is it the least used station on the line?
Other reason i can think of is that its operational related?

The Sunday timetable has, for many years, been based on only 2-tracks available between Liverpool Steeet and Shenfield, instead of 4-tracks. The omission of the Maryland stop is simply to speed up the service slightly so that the following Greater Anglia train doesn't get unnecessarily delayed.

thanks for the answers
is there a specific reason its based on 2 tracks and not 4?

thanks for the answers is there a specific reason its based on 2 tracks and not 4? Crossrail work and the replacement of the overhead line equipment are the latest causes. Lifts are being installed at Maryland at the moment as well as other work and the platforms are very narrow. |

thanks for the answers is there a specific reason its based on 2 tracks and not 4? Unlike LU, the mainline system generally doesn't have the concept of engineering hours, where routine maintenance work gets done. This is partly because mainline services tend to run a little later and start earlier than LU, plus add in empty stock moves and freight trains. Every section of line therefore needs a strategy for how routine maintenance will be planned and carried out. With the mainline often being more flexible than LU in having diversion routes and multiple tracks available, these strategies may involve planned Sunday closures on a cyclical basis (especially Saturday night into Sunday morning), planned diversions over alternative routes, or closing particular tracks on a multi-track route. In this case, having the timetable based around only two tracks being available allows either pair of tracks to be blocked without having any impact on the timetable, apart from the obvious lack of resilience if things go off book. |

I don't know if it still runs that way but when I lived out that way from the 60s to the 80s the GEML from London to Shenfield ran 24*7 and any overnight or weekend engineering took out only one pair of tracks. It makes sense to schedule services in the main engineering period on the assumption that only pair of tracks is operating.

There are a lot of them at the moment but they tend to run on the fast lines except when possessions are taken for Crossrail work. It is common for the last 2 or 3 down and first up TfL services to run on the fast lines too. |

If the fast lines are closed so that InterCity etc trains which use them are instead using the electric lines then it is sometimes possible to see cross platform interchange between central Line tube trains and mainline InterCity trains.
Its great that especially if going west, towards Liverpool Street Station, passengers from the Underground trains can nip across to the other platform and travel in style, visit the buffet (if such still exist on those trains and are still open) etc.
It makes changing trains again at Liverpool Street worthwhile.

i think the class 345 units will be 9 cars long? How does this compare to a 12 car 315 (yes i know they as 8 car usually)?

7 car 345 will run into Liverpool Street from Shenfield from May. This will be longer than an 8 car 315.
Can't get a 9 car 345 into Liverpool Street until platforms are extended once the service starts running under London.
A 9 car train at Maryland will require selective door opening.

How does this compare to a 12 car 315 (yes i know they as 8 car usually) Do they ever run as 12 car? The 306s they replaced were 162m for a 3x3-car formation, marginally longer than a 2x4-car class 315 train. |

The 306s they replaced were 162m for a 3x3-car formation, marginally longer than a 2x4-car class 315 train. Possibly as ECS, but in service I think they'd be too long for all of the intermediate stations (generally 170m to 190m long) on the Liverpool Street to Shenfield route. |

Since the TfL Rail takeover they only run as 8 car.
This keeps things simple.
Most of the platforms out to Shenfield are only long enough to take the existing 8 cars and are being extended to accommodate the new 9 car trains.

I suspect that whilst they may have been slightly longer, they would have carried fewer passengers... as a result of 3 x sizable guards compartments (under the pantograph - I was inside 306 017 a few months back) and 6 x cabs (2 more than the 315s). |
