Pain in the arse when using a wheelchair.....no one's thought of those!
Presumably that depends on where you are and which way you are going relative to the tactiles. The relevant provisions are in the NTSN: Persons with Reduced Mobility (
PRM▸ ):
4.2.1.4. Floor surfaces
(1) All floor coverings, ground surfaces and stair tread surfaces shall be slip resistant.
(2) Within the station buildings there shall be no irregularities in excess of 0,5 cm at any given point in floor walking surface areas, except for thresholds, drainage channels and tactile walking surface indicators
The provisions about danger area marking that the exemption was granted for say:
4.2.1.12. Platform width and edge of platform
(6) The boundary of the danger area, furthest from the rail side edge of the platform, shall have a visual marking and tactile walking surface indicators.
(7) The visual marking shall be a contrasting, slip resistant, warning line with a minimum width of 10 cm.
(8) Tactile walking surface indicators can be one of the two types:
- an attention pattern indicating a hazard at the boundary of the danger area
- a guiding pattern indicating a path of travel at the safe side of the platform
As I read that one it's not saying the wayfinding tactiles are required. There are, however, a lot of complicated bits about obstacle-free routes that may, taken together, require one along a platform (though so far I think that's slipped past not-quite-specified).
The NTSNs are based on the TSIs, rather than previous
UK▸ rail standards. They were put together mainly by
RSSB▸ , but this one appears to have been written by consultants (specifically someone from Ricardo with previous experience at the EC and
ORR» . RSSB are providing guidance about impmenting bits of them even in upgrade works where it's not a requirement, in which case these NTSNs might result on more compliance with the TSIs than would have happened otherwise (i.e. without Brexit).
This is the page with the NTSNs in it (filed under Brexit, not
DfT» ).
