Piccadilly line closures to hit weekends and school holidays as TfL tests
new trains

https://www.ianvisits.co.uk/articles/piccadilly-line-closures-to-hit-weekends-and-school-holidays-as-tfl-tests-new-trains-89860/

Transport for London (TfL) is warning of a series of closures on the
Piccadilly line over the next few months as it upgrades the line for new trains.

These partial closures will allow TfL to carry out upgrades to the power supply, tracks, platforms, depots, and sidings while continuing to test the
new trainsrCO interactions with existing London Underground infrastructure, alongside assessments of their efficiency and performance.

Work already completed during previous closures of the line includes weight-load testing of the new trains, with 400km covered using a test
train in its fully loaded state of 68 tonnes, and work at 119 Piccadilly
line platforms to ensure they are ready to accommodate the new trains,
which are longer than the current fleet and have different door placement.
Some of the closures are also being used to continue routine maintenance
work, such as the renewal of points in the Hounslow area.

Most planned closures will take place at weekends, with many starting from 00:30 on Saturday mornings (meaning Friday Night Tube services are
suspended) and continuing until the end of service on Sunday.

However, there will also be some mid-week closures, and TfL said that where possible, the weekday closures have been scheduled for school holidays,
when demand on the network is significantly reduced.

68 tons? that can't be right. I know they're lighter than the 73 stock
but less than 50% of the weight is implausible. 73 is 140 tons IIRC.

But its when all the UK tourists pile into london.

I think 68 tonnes is just the simulated load, not the crush loaded train
weight (244t).

I know they're lighter than the 73 stock
but less than 50% of the weight is implausible. 73 is 140 tons IIRC.

TheyrCOre about the same empty weight (73 158t, 24 157t), despite the extra length of the 24TS and the aircon.

68 tonnes of sandbags/pretend passengers ?
Roughly 900 virtual passemgers at 12 stone each?

I was expecting a bit more weight saving than that. Yes its a bit longer
but its also saving on a few bogies too and they're not light.

10 bogies rather than 12. 113m compared to 106.8m.

From Heathrow, with possible use of other rail
lines, not that many from Cockfosters or Uxbridge.

Correct. Just over 1,000 passengers. 68 tonnes divided by 1000 -> 68Kg.

I don't know about tourists but cockfosters is - soon to be was *** - a
popular commuter station for people living north of london.

*** Sadiq Kunt in his wisdom is getting rid of the carpark to build flats
on it to make some more money for TfL. Presumably he expects all the
commuters to pile onto Thameslink at Potters Bar where the resulting crush loadings won't be his problem.
