However, with reading issue 731, I feel the problem is now worse than ever - I am talking about the mix of imperial and metric units...
It starts on page 13, where NR are increasing 29,156 yards of track speeds. Including 2,244 yards at Askham from 115 to 125mph. A little lower down a new 246 metre viaduct is being constructed at Doncaster.
On page 15 the train involved in the Stoke Lane derailment ran for approximately 850 metres, while on page 16, 30 chains of track are being retained at the Tytherington branch, while six miles will be closed, but 17.5 kilometres of new tram tracks are being built in Nottingham.
On page 21, ten miles of track are being replaced on the welsh border, and a 132 metre section of tunnel is being reopened in Birmingham, yet over the page 6km of track and 3km of Victorian era drainage was replaced on the Tyne and Wear Metro, and a new loop capable of taking a 775 metre train is being installed at Eastleigh (would a 775 metre train fit into the 30 chains of track being retained at Tytherington)?
On Page 24, 1km of new railway is being installed at Bicester, and on page 27 the s-stock trains are 2.5 metres longer than the trains they replace.
Then moving on to the (excellent) infrastructure article, we find on page 66 NR replaces 500 miles of track a year, and the renewal machine exposes 60 yards of track at one time, but cuts the old track into 90 metre lengths.
6 miles of new tracks were laid at Nottingham (p.74) Things get really silly on p.77 when boxes are either 2,500mm or 2,600mm wide and either 9ft or 9ft 6in high, and wagons are 18.3m long with a bogie spacing of 14.02m...
We are back to 3km of track being replaced at Gosforth on page 80.
The electrification article on page 85 then refers to 900 miles of railway to be electrified by 2020, of which 235 miles will be on the great western, 325 km elsewhere and then goes on to mention a further 156kms (sic) in Scotland.
Congratulations! With a reference to acres for a new station at Harrogate on page 13, your articles in this edition have managed to list units in: millimetres, inches, feet, yards, metres, acres, chains, kilometres and miles.
Will you please have another look at your style guide and adopt either one system or another (especially within the same article)?
