You may have missed the numerous times I've referenced the December 2017 RSSB report into mobility scooter access to trains. If they meet the size requirements that apply to wheelchairs then they are, for the purposes of legislation, classed as wheelchairs too.
GWR's policy, (which is not a legal requirement) is seemingly at odds with this.
And I'll say this again too. Regardless of any policy, Tanyalee Davis and her mobility aid were boarded and settled at Plymouth, into a unreserved disabled space, without issue. Retrospective application of a company policy after that should not happen. And certainly not happen to accommodate a pram.
And once more. GWR have said unequivocally that this should not have happened.
So essentially, you're suggesting that GWR's own policy of requiring even small mobility scooters to be folded and stowed as luggage is itself a breach of the Equality Act?
Would someone in a foldable manual wheelchair who can transfer to a seat be "immune" (for want of a better word!) from requests to fold their wheelchair, if it was sat, unfolded, in the wheelchair space, and another wheelchair user who could not transfer boarded?
Whatever the intricacies of the law, we can both agree that being asked to move your mobility aid for a pram is quite egregiously wrong.
