These are not the only options – I have seen many buggy users helped on many occasions by others to get up and down stairs at both ends.
Furthermore, for those people forced to make their perambulations in a slow fashion, they will be significantly worse off in a closure that requires them to make a longer walk and deal with the gradients on the South Circular.
Is there a problem in asking for clarity on the revised programme and thereby seeking certainty that any required closure is kept to a minimum duration and therefore diminishing the impact on the disadvantaged users ?
Thinking this through, perhaps the issues raised here lead to a very serious question that asks why we do not address the issues provided for under the Equalities Act. This Act now requires that those protected by DDA legislation be further protected by pro-active consideration being given to not denying them equal access to all features and facilities that everyone else enjoys.
Certainly not during the course of the works and perhaps now also for any permanent redesign of the subway,
I cannot see that any reasonable person would not want to seek solutions to difficult issues at both of these levels even though no positive outcomes can ever be guaranteed.
