Better regulation and clearer laws will no doubt help - the current free-for-all cannot continue. 

If you pass laws that make JustEat and the like directly responsible for ensuring their riders use proper equipment (perhaps by supplying it, or offering incentive schemes through approved retailers) and don't break the law then that will help enormously IMHO^▸ (in my humble opinion).  Forcing them to provide proper contracts of employment rather than treating them as contractors and letting them get on with sourcing their own bikes and (lack of) equipment will also help.  Being paid per delivery only encourages them to buy unsuitable equipment and ride it irresponsibly.

It might end up making their businesses unviable which is tough.

Is this a repeat showing?

Khan is first and foremost a politician. As the infrastructure failures also affect all traffic on the Great Western Main Line it is, at best, disingenuous to imply that it’s only the Elizabeth line that is affected.

If he can imply that the blame for the failures lies with Network Rail the implication is that it’s actually the fault of the Government for being tight fisted. He is Labour and the Government is Conservative so why am I not surprised by his statement? He is also playing the ‘fares freeze’ game again. In January he announced that TfL^» (Transport for London - about)’s fares will be frozen for the current year, see this press release https://www.london.gov.uk/mayor-steps-and-announces-hell-freeze-tfl-fares-year-easing-cost-millions-londoners

What he doesn’t mention is that as a result there will be a shortfall in TfL’s income (again) which will inevitably result in another call on the Government for more support for TfL's investment programmes.

For what it’s worth I reckon that the Great Western has been undermaintained over the last fifteen years or so due to lack of engineering access caused by the Reading station rebuild, the construction of the extra flyovers at Stockley and the flyunder at Acton as well as the electrification work west of Airport Junction and transfer of the signalling control to Didcot. After a while all this deferred maintenance shows its ugly face and with the increase in the number of trains running getting onto the tracks to do stuff is getting more and more difficult.

If Khan was serious about getting the infrastructure more reliable he would meet Network Rail, GWR^▸ (Great Western Railway) and the freight operators half way and offer to cut the number of trains operating dramatically in those hours when maintenance is possible.

If not, then it’s only grandstanding.

PS: The original electrification was not done on the cheap - it was designed and installed to cope with four multiple unit trains per hour in each direction. It worked as designed very well until the number of electrically powered trains rose dramatically.

Transport Secretary Mark Harper described it as a “serious incident”. Tory mayoral candidate Susan Hall called on Sadiq Khan, who is the TfL chair, to “make a full apology to those affected”.

“What happened on the Elizabeth line was undoubtedly distressing for thousands of passengers. I hope TfL gets to the bottom of how this happened, so it can ensure this never happens again.”

I guess the suitability of any simplification will depend on whether the government wants to simplify fares to encourage more people to travel by train and ensure fewer people buy the wrong ticket.

Or or they want to put people off travelling by train with higher fares so they might be able to reduce the cost of the railway by reducing services and/or closing lines/stations or effectively remove the ‘walk up’ railway principle on longer distance routes.
