'''News, Note and Comment''' *The Turakina Deviation will be opened use on Sunday7/12/1947 and existing stationa at Ratana, Whangaehu Bakers Crossing and Fordell will be closed. No opening ceremony is anticipated. the new alignment includes three tunnels and two bridges The two new stations Fordell and Whangaehu will have Tablet instruments with Whangaehu having a switch-out option. Distant signals will be colour light and home signals Semaphore, with points operated by frame levers. Distances from Marton are now: Turakina, 10.8miles; Whangaehu, 13.2 miles;Fordell, 18.1 miles, Okoia, 22.4 miles; East Town 26.2 miles; and Aramoho, 27.1 miles. Train timetabling will see significant changes, Train 507 departing 18 minutes later; Train_610 will leave Marton as at present but arrive at New Plymouth 18 minutes earlier. The track off the old formation is expected to be used on a new line from Putaruru towards Reporoa for forestry traffic. *The first of the 3,000 La_class_wagons arrived in August and September and are being assembled in the Workshops as quick as possible. 15 have been completed at Otahuhu Workshops by 11 October, and are being numbered from 21956 onwards; 31 have been completed at Addington Workshops and are being numbered from 23456 onwards. These wagons show only a little rivetting, and have a triangular section around the top edges rather than just an angle. *A special train ran from Wellington to Gisborne on 11/09/1947 for the opening of the Ngarimu Memorial Meeting House in honour of Lt Moananui-a-Kiwi Ngarimu VC (for gallantry at Tunisia). The running time allocated in both direction was significantly less than for Express services. *Tractive Effort of Steam Locomotives. The standard formula for a 2 cylinder simple locomotive is d<sup>2</sup> x S x p / D where d = diameter of cylinders, S = piston stroke, p = working steam presure, D = diameter of driving wheels. The October 1938 issue of The Railway Magazine addresses the subject in more detail, or see wiki page [[Locomotive Tractive Effort]] *Midland Line Engine load ratings, 340t is the maximum load for a Kb_class_loco on the steepest parts of Springfield to Arthurs Pass. *The Hunslet loco seen at Frankton is one of three belonging to the PWD but being used and charged to NZR in the meantime. They are 0-6-0T, 13" x 20" 6 wheel coupled 3"-4" diameter 160psi with total weight 22.5t. Preservation of old locomotive *Josephine is to be given a tidy-up ahead of the Otago Centennial celebrations. *Loco_A62 (with plates 196) at Otahuhu workshops has been painted a bright aluminium, while loco_Wd320 about 100 yards away has a 'less-said-about-the-better' colour. *Tramcars and Trolley Busses. A Canadian correspondent sees the switch from Trams to Trolley as a backward step, with Trams having far more safety advantages and should just be modernised rather than replaced.
