Development near a level crossing and Network Rail

If your site sits near a level crossing and your scheme will add users to it, the rail infrastructure manager will object unless you can show the crossing risk does not rise. That is the practical position, and it catches developers who assumed the railway was a boundary issue rather than a capacity one.

Crossing risk is calculated from how many people and vehicles use the crossing, how often trains pass, and how the crossing is controlled. Add fifty houses on the wrong side of a footpath crossing and you have changed one of those inputs.

When the rail infrastructure manager is consulted

Network Rail is a statutory consultee for certain development affecting the operational railway, and it is consulted by local planning authorities on a wider range of proposals under standing arrangements. In practice you should expect consultation where the site is adjacent to the railway boundary, where access would cross or pass over railway land, where development would increase use of a level crossing, or where the proposal involves works near a structure carrying or crossing the line.

Crossings on other networks work the same way through the relevant infrastructure manager, and light rail and heritage railways have their own arrangements.

The consultation response is not a formality. Objections on crossing risk are sustained at appeal, and inspectors treat safety evidence from the infrastructure manager seriously because it comes with the operational data behind it.

How additional users change crossing risk

Crossings are assessed using a risk model that combines the number of pedestrian or vehicle movements, train frequency and speed, sighting distances, the type of protection in place, and the history of misuse and near misses at that location.

A new development changes the first input directly. It can also change the character of use, which matters more than the raw number. A crossing used twice a day by a farmer behaves differently from one used by schoolchildren, dog walkers and pushchairs at predictable peaks, because the behaviours that cause incidents are different.

The crossing types that generate the most objection are:

• user-worked crossings with telephones, where the user must call the signaller
• footpath crossings with no protection beyond sighting and signage
• open or automatic crossings on higher speed lines
• crossings where sighting is already restricted by vegetation, curvature or structures

Automatic half barrier and full barrier crossings are more tolerant of additional users, though they bring their own problem, which is queueing on the approach when barriers are down.

Evidence the operator will expect

Start with movements. The Transport Assessment should quantify additional pedestrian and vehicle movements across the crossing specifically, not just across the network generally, and that means a route assignment rather than a total. On a smaller scheme the same analysis sits in a Transport Statement.

Beyond that, expect to be asked for:

1. A survey of existing crossing use, by mode, at representative times and on a neutral date.
2. The assignment of new trips, with the assumptions stated, showing what proportion would use the crossing.
3. Sighting distance measurements taken on site, with photographs from the user's eye height.
4. Consideration of desire lines, because people take the shortest route rather than the designed one.
5. Any proposed mitigation, costed, with the delivery mechanism identified.

Trip assignment is where these cases are won and lost. An assessment that assumes nobody will use the crossing because a longer road route exists will be tested against the desire line, and a plan showing the crossing as the obvious route to the station, the shop or the school will not survive that test.

Mitigation: diversion, bridging and closure

Four routes, in ascending order of cost.

Improving the crossing itself. Better sighting through vegetation clearance, improved decking and gates, additional signage, or an upgrade in the protection arrangement. The lowest cost option, and the infrastructure manager decides whether it is enough.

Diverting the public right of way to an existing safer crossing. This needs a diversion order under the Highways Act 1980 or the Town and Country Planning Act 1990, with its own consultation and objection process, and it takes months to years.

Providing a new bridge or underpass. Expensive, and constrained by gradients, accessibility requirements and land. A footbridge that complies with accessible gradients needs far more land than people assume, which is often the reason this option fails on a small site.

Closing the crossing, usually combined with one of the above. Closure needs an order and is resisted by user groups, and it is the outcome the infrastructure manager generally prefers.

Whichever route applies, secure it properly. A section 106 obligation with a trigger tied to occupation, a contribution calculated by a stated method, and a fallback if the works cannot be delivered. A condition requiring works on third party land with no mechanism to deliver them is unenforceable and will be resisted.

Boundary treatment and trespass

Separate from crossing risk, development next to the line brings a trespass and incursion question.

The infrastructure manager will expect a boundary treatment agreed with them, typically a fence of specified height and construction set inside your boundary, with no gates or access points onto railway land, and maintenance achievable without entering the operational railway. Expect requirements on planting, since trees close to the boundary create leaf fall, wind throw and climbing risk.

Other standard points: no scaffolding, cranes or piling within an agreed distance without an agreement, no drainage discharging towards the railway, no lighting capable of being mistaken for a signal or of dazzling drivers, and construction traffic routes near crossings need managing, which links to the wider arrangements covered in the note on temporary road closures and street works.

Some of these become conditions, and some become an asset protection agreement with the infrastructure manager, which is a commercial agreement outside the planning permission and carries its own fees and timescales.

Noise and vibration from the railway

The direction of effect reverses here. The railway is the source and your housing is the receptor, and the infrastructure manager will not accept a scheme that creates a complaints problem against an existing operation.

Expect a noise assessment with measurements over a period covering both daytime and night-time train movements, an assessment of groundborne vibration where the line is close or the geology transmits it, and a mitigation scheme covering glazing, ventilation and layout. Internal noise criteria come from the relevant British Standard, and the assessment should also consider external amenity space.

Layout mitigation is better than glazing mitigation. Putting circulation, bathrooms and kitchens on the railway elevation and habitable rooms away from it solves the problem at no running cost, and it is a decision that has to be made at massing stage rather than at technical design.

Programme risk and early engagement

Rail consultation responses take time, and the follow-up work takes longer.

Engage before the layout is fixed. A pre-application enquiry to the infrastructure manager, with a site plan and an estimate of additional crossing users, will tell you early whether the scheme is deliverable as drawn. That conversation costs nothing next to redesigning after a consultation objection.

Build the sequence into the programme: pre-application enquiry, crossing use survey on a neutral date, trip assignment, mitigation discussion, then the asset protection or diversion process running in parallel with determination. Diversion orders and closure orders do not fit inside an eight or thirteen week determination period, so they need to start early or be secured by obligation.

And put the crossing question into the site appraisal at acquisition. A scheme whose viability depends on a footbridge is a different proposition from one next to a full barrier crossing, and the difference is visible from an aerial photograph and a timetable.

This is general guidance, not legal advice. Crossing risk assessment, noise and vibration assessment and asset protection agreements need suitably qualified input, and you should check the position with the relevant rail infrastructure manager and your local planning authority.
