LTS
Speed Limits
LTS speed limits are complex with as many as four different speed limits for one section of track. The following gives a broad overview and is not complete.
Main Line
The Main Line maximum speed is 75mph with 70mph for wrong-line running on the bi-directional sections, for multiple units only. There is a 20mph speed restriction through Limehouse in both directions due to the sharp curve, and 20-30mph restrictions around Gas Factory Junction for the same reason. Non-multiple unit trains are limited to 25mph maximum between Fenchurch Street and Barking, and mostly 50mph between Barking and Shoeburyness with some sections of 25mph to 40mph.
The crossovers at Dagenham East are 40mph over either in the reverse position.
The main line crossovers at Upminster are 15mph in the reverse position. The connection to the Ockendon branch is 20mph with the bay platform 15mph.
The crossovers at West Horndon are 40mph over either in the reverse position.
The west end of the centre Laindon platform is rated at 15mph to/from the Up line and 30mph to/from the Down line. The east end is 25mph for both connections.
All three main line crossovers at Pitsea are rated at 15mph. Multiple Units are limited to 60mph through Pitsea main line platforms due to curvature.
The middle platform at Leigh-on-Sea is limited to 20mph for all four connections and through the platform itself.
Between Leigh-on-Sea and Southend East, the speed limit drops for all trains. This is due to curvature, short sections, and gradients.
The three main line crossovers and the two bay platforms at Southend Central are limited to 15mph for all trains.
The station throat and platforms at Shoeburyness are limited to 15mph for all trains.
Ockendon Branch
The Ockendon branch is rated at up to 60mph with a lower limit for non-MUs. The loop platform at Ockendon is limited to 15mph over the pointwork at the London end and 40mph for the platform and east end connection.
Between Grays and West Thurrock Junction in both directions, it makes barely any time difference to use the Third Line or the Up/Down Tilbury lines.
Tilbury Loop
Most of the Tilbury Loop is limited to 50mph for non-Multiple Units and up to 60mph for Multiple Units. Between the former Tilbury East Junction (just to the east of Tilbury West Junction) to Pitsea is up to 70mph for Multiple Units.
Ripple Lane is mostly 15mph once off the Up Tilbury and Down Tilbury, with the exception of the area around, and connections to/from, the Exchange Sidings.
The connections to Seabrook Sidings near Grays are limited to 15mph.
From the Up Tilbury to Ockendon the speed limit is 50mph compared to 50mph for non-MUs and 60mph for MUs for the line towards Purfleet. The Down Tilbury to Third Line connection limits trains to 30mph.
Just to the east of Tilbury West Junction is the former Tilbury East Junction. Between the two there is a sharp bend which limits all trains to 20mph in both directions. The two junctions used to form a triangle with Tilbury Riverside station where Riverside Sidings now exist (with the former east connection severed). Tilbury West Junction is 15mph for trains going to and from Riverside Sidings.
The connections to the Thameshaven Branch are rated at 25mph with the branch itself 40mph.
The crossover at Stanford-le-Hope is limited to 25mph.
