That only gets us back to where we were before covid, which is nowhere near enough. Crossrail 2 needs bigger growth than that, and starting from pre covid levels, not what we have now.
And we have yet to see what impact artificial intelligence has on London commuting.
Indeed, however 2% growth for rail is fairly low for most of the last 20 years.
For example the baseline model for HS2 was 2.5% and between 2009 and now we're pretty much on track with this last years numbers for London to the West Midlands (150 passengers in 2025 for every 100 in 2009 vs the 145 that 2.5% growth predicted) and that's the lowest of the three regions for HS2 (North West is 160 and Scotland is 257).
Of course the other factor to consider is not just what was happening at the time of Covid but at the time of the formal launch (May 2013).
At the time travel between London and the East of England was around the 120 million mark and had seen growth and drops in the previous few years so was around the 105 million to 112 million between 2007 and 2011 (with the low point in 2010) that still averaged 2.9% growth.
Compare that with 2025 which is 128 million (so already above what was seen in in the year to March 2013 - although they are likely to have been using the previous year's data due to the time needed to create the information for a full launch in May 2013).
Between 2024 and 2025 there was growth of 5.7% and whilst this was much lower than previous year (15.3%) that was still basically being is back from Covid (interestingly basically the same annual passenger numbers as the low in 2011 to the 2013 numbers but withthe growth in just one year).
Whilst 5.7% is unlikely to be sustainable getting somewhere around 3% (same as the 2006 to 2013 period) probably is and that's still less than the average growth of 3.55% growth between 2013 and Covid.
By saying that wecould get to pre Covid numbers by 2030 by not having to breach 2% growth I was saying that target should be easy to reach, and so there's scope for there to be some growth.
Doing some digging from the East of London there's two lots of growth assumed, the first is baseline growth of up to 1.3% (so even lower than 2%) the second was the delivery of 100,000 new homes in the upper Lea Valley and Hertfordshire.
Specifically 20,000 between 2020 and 2026. However, due to the pause on Crossrail 2 (so there's not the potential capacity due in rail just around the corner as well as Covid slowing construction) it's made it hard houses to be delivered, with only around 2,000 being delivered.
As such between 2013 and 2020 (limited housing) the model expected 9.5% growth (7 years of 1.3% growth) what was seen was 23.2% so way more than expected and sightly more than expected over 16 years of growth (i.e. to 2029).
As such meeting the pre Covid numbers in 2030 probably isn't too far off what the modeling was expecting if house building doesn't pick up significantly (and that's only likely if Crossrail 2 is unpaused).
If growth is sustained at rates much higher than 2% (for example with the large house building in place the annual growth rates were 2.6%) so if we see ongoing growth of over 3% between now and 2030 with limited house building then arguably we'd be ahead of the Crossrail 2 model for eastern side.
From 2013 to 2025 the 1.1% to 1.3% growth rate would have expected 114 to 117 by 2025 (up from 100 in 2013) and whilst that's currently only 106 if 2026 and 2027 see sightly lower but similar growth rates (circa 5.4%) to 2025 (5.72%) then the actual would be close to what the model was expecting.
However, scale this out to 2030 with an average rate of 3% each year between 2026 and 2030 and we'd be at 123 passengers per 100 in 2013 vs 1.1 growth predicting 120 with 1.3% predicting 125.
As such, if we see growth rates fall from the current 5.72% (highly likely) but still be above 3%, then things on the eastern side of London also could be good enough to justify unpausing Crossrail 2.
Clearly, there's a need to reach pre Covid numbers and then a bit more, however as I hope the above shows, as well as the other points I raised in my post covering other areas of concern, that's entirely possible and so Crossrail 2 isn't quite a dead in the water as some imply.
Yes it may not start until 2040 or even 2050, but that's not that much different to 2013 to early 2030's if it gets unpaused within the next 5 years.
