    186 MAY 1887. ON THE CONSTRUCTION OF CANADIAN LOCOMOTIVES. BY MR. FRANCIS R.- F. BROWN, OF MONTREAL. In the present paper the writer purposes dealing morc particularly with those classes of Locomotives wbich have been built from his designs and under his personal supervision at the shops of the Canadian Pacific Railway, Montreal. A few preliminary remarks are desirable, in order to present the subject on a fairer basis for comparison with English practice. The permanent way in Canada consists generally of flat- bottomed rails, weighing from 56 lbs. to 72 lbs. per yard according to class of service and age of road. The rails are spiked to flattened ties or sleepers at about 2 feet centres, or closer if necessary. Either common or angle fish-plates are used ; and brace castings are placed against the outside rails at curves as required. Grades are usually expressed in percentage, or in ft. per mile ; and curvature in degrees of the anglc subteuded by a 100-ft, chord on the curve ; thus a curve of 1" has a radius of 5,730 feet, and a 5730 curve of 6" has a radius of 7= 955 feet. The maximum grades on main lines are commonly 1 per cent. or 52.8 feet per mile, and the sharpest curvature 6" or 955 feet radius ; these limits of course do not apply to mountain sections, The classes of service comprise :-way or stopping freight, that is, goods trains; through or fast freight ; mixed, that is, one or more passenger coaches attached to freight trains for local country service; local passenger; and express.

When, ten days ago, the first copy of the " Evolution of the Steam Locomotive" was ready for sale, I did not expect to be called upon to write a preface for a new edition before 240 hours had expired. The author cannot but be gratified to know that the whole of the extremely large first edition was exhausted practically upon publication, and since many would-be readers are still unsupplied, the demand for another edition is pressing. Under these circumstances but slight modifications have been made in the original text, although additional particulars and illustrations have been inserted in the new edition. The new matter relates to the locomotives of the North Staffordshire, London., Tilbury, and Southend, Great Western, and London and North Western Railways. I sincerely thank the many correspondents who, in the few days that have elapsed since the publication: of the "Evolution of the , Steam Locomotive," have so readily assured me of - their hearty appreciation of the book. rj .;!

    Oxford Rail Adams Radial Tank EM Finescale Conversion. Before you start, it is a good idea to have some small containers or snap top poly bags to put screws and components in for safe keeping......much better than crawling about on the floor trying to find lost bits! LOCO CONVERSION 1. With the loco inverted and well supported, first undo the bogie retaining screw and lift the bogie clear from the loco. Be careful, as there is a spring and plastic washer underneath! We replaced the screw in the chassis, which also retains the spring and washer so these do not get lost. Bogie removal 2. Slacken crankpin screws and remove the coupling and connecting rods. The connecting rods can be left dangling, and the coupling rods are identical each side, so do not need to be marked left and right! Coupling rod removal 3. Undo the screws holding the keeper plate, and lift away. The brake linkage at the rear under the cab gets in the way a bit, but it will come off the chassis easily, making life a bit easier. Keeper plate removed. 4. It is worth looking at how Oxford have designed this chassis. The driving wheels are on 2mm diameter axles, running in very nice brass bushes. All very standard apart from the axle size! As Oxford built it…. 5. If we now lift out the wheels, we find a very well cast pair of slots for the bearings to sit in……these just happen to be exactly the right size to take a standard 1/8 inch axle.

Coupled to a short wheelbase and guiding bogie, the locomotive could accommodate tight curves, a feature that was to ensure the survival of some of the class later on. The 0415's tenure on the London suburban services was relatively short-lived and with the introduction of Drummond's M7 class 0-4-4 tanks and the class was generally removed to rural branch duties from 1895. In 1903 the link was made between the class and the severely curved Lyme Regis branch where the 'Radials' proved to be highly suited to that line. Two were allocated to Exmouth Junction shed, joined in 1946 by a third example retrieved from the East Kent Railway. They continued on the Lyme Regis branch after Nationalisation but the end finally came in 1961. However the final example, No. 30583, was purchased by the Bluebell Railway and preserved. The model is 1:32 scale for 45mm gauge track, gas-fired with a single flue boiler. The chassis is constructed from stainless steel, the wheels are uninsulated. The boiler is copper, the cab and bodywork are constructed from etched brass. The model will run round 4′ 6″ radius curves (TBC).

  • Modelling of a Passive Hydraulic Steering for Locomotives
    Modelling of a Passive Hydraulic Steering for Locomotives by Torsten Peter Löwe Submitted in partial fulfilment of the requirements for the degree Master of Engineering in the Faculty of Engineering, Built Environment and Information Technology (EBIT) University of Pretoria, Pretoria October 2014 (Lard, 2013) 1 Modelling of a Passive Hydraulic Steering for Locomotives. Candidate: Torsten Peter Löwe Supervisor: Prof P.S. Els Co-Supervisor: Dr C. Kat Department: Mechanical and Aeronautical Engineering Degree: Master of Engineering Abstract During the past few decades, substantial improvements were made to rail infrastructure worldwide. This was necessary to accommodate the ever increasing transportation demand and requirements. Nowadays, trains are required to transport heavier loads and to travel at higher speeds. One of the major improvements was achieved by the development of the off-flange curving bogie designs to reduce wheel and rail wear. Off-flange designs include passive steering and actively controlled steering. The development and implementation of self-steering bogies on locomotives was promoted in the early 1980’s by two major locomotive manufacturers. Up to date, thousands of these locomotives, with built-in self-steering bogies, have been manufactured and taken into service (Swenson, 1999). Most self-steering bogies have mechanical linkage systems to steer the wheel sets. As an alternative to the mechanical linkage system, the DCD Group (a South African manufacturer of rail and mining equipment) initiated the development of a Passive Hydraulic Steering (PHS) system. First PHS prototype systems, developed by DCD, have proven that huge wear reduction possibilities exist on both, rails and wheels. In addition the prototype systems also significantly decreased noise and vibration levels when negotiating tight corners (Swenson & Scott, 1996 and DCD Rolling Stock, 2012).

  • ADAMS RADIAL TANK 4-4-2T LIMITED PRODUCTION • 1:32 SCALE • 45 Mm GAUGE
    ADAMS RADIAL TANK 4-4-2T LIMITED PRODUCTION • 1:32 SCALE • 45 mm GAUGE S32-15A L&SWR Adams Green #488, Full Lined William Adams’ 415 (later 0415) Class was based on his earlier LSWR 46 Class, with London suburban services in mind. The design was based on a 4-4-0 design with a trailing radial axle added to support an enlarged coal bunker. The radial axle box worked in a corresponding curved horn block the centre of which was struck near the middle of the chassis. Many tank engines so fitted earned the soubriquet ‘Radial Tanks’, or simply ‘Radials and the 415 Class was no exception. The enlarged coal bunker was also designed to incorporate a back tank for extra water storage in addition to the capacity of the side tanks. Coupled to a short wheelbase and guiding bogie, the locomotive was relatively manoeuvrable on tight curves, a feature that was to ensure the survival of some of the class later on. Production began in 1882 when a total of four engineering companies were contracted by the LSWR to construct the new class, which numbered 71 when production ceased in 1885. These were: Robert Stephenson & Co., Dübs & Co., Neilson & Co. and Beyer, Peacock and Company. This arrangement was because Nine Elms, the LSWR’s own locomotive works, was already stretched to capacity in terms of production. Our model is based on the Neilson batch, readily identified by the curvaceous frames in front of the smokebox. Upon the appointment of Dugald Drummond as Superintendent of the LSWR after Adams’ departure, the class was modified slightly, with the application of his lipped chimney in place of the stovepipe version that the locomotives were equipped with when built; in due course they also acquired Drummond boilers with the safety valves incorporated into the dome.
