Roger Ford's annual tables of performance for different classes of train have just been published in January's Modern Railways.
FGW▸ HSTs▸ period 7 moving average 2008/9 = 11,501 miles 2007 = 9624
XC▸ HSTs period 7 " " " = 9,623 2007 = N/A
Best overall IC▸ is ECML▸ with 24,317. Could it be that loco and coaches gives better performance?
To compare and electric traction unit against a diesel traction unit is not a fair comparison. electric traction units have far less moving parts than diesels therefore require less maintenance and the maintenance is of a short duration. An industry study has recently been done to compare the reliability of an electrified railway compared to a non electrified railway, because of the perception that OHLE is unreliable I don't have the figures to hand but it came out that electric traction failure and maintenance rates per Km was far lower than diesel even though the infrastructure requires a higher level of maintenance this is more than compensated for by the very much lower maintenance and failure rates of electric traction units.
Excellent that's exactly why I put the IC 225s in as a comparison.
When can you start slinging the wires?
As an aside it seems interesting that the ECML doesn't seem to be having as much OHLE trouble now the Eurostars aren't running. Something about higher pan pressure?
The pans on Eurostars were designed to run predominately in France so the pan pressure could be higher, also the French rail system uses copper contacts on their pans were as we use carbon in the
UK▸ .
As for stringing the wires up comes down to money and time, the big OHLE projects currently are Liverpool St to Shenfield to replace some equipment that was erected before WW2 that was converted to 25 kV also ECML is being refurbished and there is work to do on parts of the
WCML▸ in and around Brum, Manchester Liverpool etc. Money is not the only scares resource designers and construction staff are in short supply the 10 years post privatisation decimated the resource we had in the UK
