Boeing Suffers New 737 Max Issue That Could Delay Return

The title of this post is the same as that of this article on the BBC.

This is the first paragraph.

US regulators have uncovered a possible new flaw in Boeing’s troubled 737 Max aircraft that is likely to push back test flights.

The FAA have released this statement.

The Federal Aviation Authority (FAA) is following a thorough process, not a prescribed timeline, for returning the Boeing 737 Max to passenger service. The FAA will lift the prohibition order when we deem it is safe to do so. We continue to evaluate Boeing’s software modification to the MCAS and we are still developing necessary training requirements. We are also responding to recommendations received from the Technical Advisory Board. The TAB is an independent review panel we have asked to review our work regarding 737 Max return to service. On the most recent issue, the FAA’s process is designed to discover and highlight potential risks. The FAA recently found a potential risk that Boeing must investigate.

Bodies like the FAA don’t take chances.

The BBC article also says this.

Other sources said the problem was linked to the aircraft’s computing power and whether the processor possessed enough capacity to keep up.

Sorry Boeing! But I’ll never fly in a 737 Max!

Transport for Wales Is Invading England

There is an article in the July 2019 Edition of Modern Railways, which is entitled TfW Targets Swansea To Bristol Services.

This is the first paragraph.

Transport for Wales Rail Services is aiming to start an open access service between Swansea and Bristol Temple Meads, commencing in December 2020.

These are characteristics of the proposed service.

  • Hourly service
  • Calls at Neath, Port Talbot Parkway, Bridgend, Cardiff Central, Newport, Severn Tunnel Junction and Filton Abbey Wood stations.
  • Sixteen services per day will run Monday to Saturday in both directions, with twelve services on Sundays.
  • Trains will be Class 170 or Class 175 diesel trains.

Looking at current times of sections of the route, I suspect that services could take a few minutes under two hours and would need four trains.

Reasons given for planning the service include.

  • Long-term political pressure.
  • Welsh ministers abandoning plans for the £1.6 billion M4 Relief Road around Newport.
  • Cross-Severn road traffic has increased after abolition of tolls.
  • Main roads on either side of the Severn are congested.
  • Increased house sales in South Wales to people who work in the Bristol area.

Incidentally, before I read the article, if you asked me, I’d have thought there would be a direct service.

My only thought about the service, is that as there will be electrification between Bristol and Cardiff, why not run a proper fast bi-mode train like a Hitachi Class 800 train or a Stadler Class 755 train. The latter of which Transport for Wales have on order, for delivery in 2023.

The Class 755 train or its Welsh cousin, could be an interesting option.

  • The distance without electrification between Cardiff and Swansea is 46 miles.
  • Transport for Wales tri-mode version of the Class 755 train could have three batteries and a diesel engine in the four slots in the powrpack car.

Could it have the capability of jumping the gap.

Birmingham Services

The article also says that, Transport for Wales are also planning to extend their services that terminate at Birmingham to Coventry.

  • Holyhead and Birmingham New Street takes three hours.
  • Aberystwyth and Birmingham New Street takes three hours
  • Pwllheli and Birmingham New Street takes five hours

As Birmingham and Coventry takes twenty minutes or perhaps a convenient hour to go to Coventry and return with a relaxed turnround, does the extension make these three long services simpler to operate?

Extra positioning services from Crewe to Coventry in the morning and return in the evening are also proposed.

These would  also suggest that improving the ease of operation of these services is the reason for the extension to Coventry.

Liverpool Services

The article also says that these services to Liverpool will be added in 2022.

  • An hourly service to Llandudno.
  • A two-hourly service to Cardiff.

It isn’t said, if one of these services is an extension to the recently launched Liverpool and Chester service.

Conclusion

The Welsh are getting ambitious.
