Notes
- The track line quality for mapping has been purposely reduced. More noticeable when zoomed in.
- There are plans to add line speeds and gradient information to the tracks.
Known Issues
- Loop Length: Not all loop lengths have been entered.
- Schedules: Schedules are not currently updated in real-time.
Loading Gauge
In simple terms the loading gauge is an envelope surrounding the train determining the maximum container that can be conveyed. This is to ensure trains do not hit bridges, tunnels, signals, other line side equipment or trains on adjacent lines.
They range from W6A (smallest) to W12 (largest), or GC in HS1/Europe (even larger). W8 allows standard containers, W9 allows pallet-wide containers and W10 allows high-cube containers. There are exceptions to these rules via RT3973/CON forms which state allows combinations of wagons and containers (with restrictions).
Using the 'Loading Gauge' option on the map highlights the lowest allowed value without restrictions. If a route is W6A and W7 but has restrictions on W8, then the line will show with a W7 colour.
Extended Gauge
The extended gauge shows the maximum allowed. If a route is W6A and W7 but W8 has restrictions, then the line will shows with a W8 colour.
High-Cube
This highlights routes where High-Cube containers can travel within the UK. It is split into carrying High-Cube containers with standard wagons (W10 - W12) and low bed wagons (W8 - W9).
As above, there are exceptions to the rule via RT3973/CON forms. For example, the Huddersfield to Stalybridge route allows High-Cube W10 containers with LDS006 CON form with 15mph restrictions.
Route Availability
Route Availability (RA) is a range from 1 to 10 ensurding even distribution of weight on wagonsm, protecting assets such as bridges. Typically the RA rating in the UK is 8.
Electrification
This highlights where routes are overhead electrified (OHLE), DC3/4th rail and others.
Proposed
Proposed is a scheme that has been confirmed to go ahead but has not been officially cancelled. These include deferred schemes.
Construction
Boots are on the ground and the it's all being built.
Length
This is the maximum trailing length of train that can be convoyed on routes. There are exceptions to the rule if a train does not have to stop at a location and does not conflict with another train - to be confirmed.
Why is length important?
Longer trains reduces the amount of lorries that are required to go via road - which relieves congestion and reduced emissions. They also make rail transport more cost-effective and viable option for freight operators.
What determines train length?
Primarily, the distance between signals. Any lengths for loops and sidings used is important, as the rear of the train cannot hang out over the main lines - preventing other trains from passing.

FAQs
How is this data kept up-to-date?
This depends on the data:
- Electrification: Following forums and media reports.
- Loading Gauge: Data maintenance tools and automation.
- Length and Weight: Periodically checking for new load books.
