Accessible lavatories
I see that the Elizabeth line has been designed for future growth, with stations built to accommodate an additional two carriages per train, as well as the potential to increase train frequency.
Perhaps we can therefore now plan for the additional carriages per train to include accessible lavatories - thus making them more comfortable and appealing to the elderly and those with disabilities, as well as recognising that these services are not just going to be used by strongbladdered commuters!
