Sorry II I am notoriously not very time aware when I am out on one of my Saturday trips. The Aircon went off first, then the crys of there are no loos started! I would say at lest 30 minutes. My other thought was what if the driver ran out of hours, presumably they would have to taxi a replacement from Paddington, Maidenhead or Reading.
BBM, my other half was at PAD» (Paddington (London) - next trains) and eventually got on a rammed GWR▸ (Great Western Railway) train to Bristol/Swansea.

I was wondering if the driver on my train would run out of hours and we'd terminate at SLO or MAI▸ (Maidenhead station) but fortunately we ran through. My fallback option was to get the 19:32 to Bristol as far as RDG‡(resolve) and then get a taxi back to TWY▸ (Twyford station) but luckily that wasn't necessary. (Another advantage of being stuck at PAD was the availability of loos!)
In these situations trains that are stranded at stations will be a much lower priority than any that are stranded between stations or in tunnels, etc. So, whilst the Elizabeth Line will deal with their trains at any location they serve, if it's a large number of trains affected I can see why you would have felt rather left alone if at a stand at Iver station.
At around 18:00 last evening I took a quick look at Open Train Times maps for the EL core section and it was noticeable that practically every train was being held at a platform, the exceptions being two trains in the WB tunnel between Stratford and Whitechapel. I understand however from Twitter that an eastbound EL train was stuck just east of Hayes and Harlington.
