An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.
Reference [3] [4]. In July 2010, the Ministry of Transportation issued Regulation No. KM45/2010, which among other things, renumbered the locomotive unit number. Under the new regulation, the unit number consisted of year of entered service and the unit number of that year (e.g. CC201 78 03 (former CC201 31) denotes that it is the third CC201 that entered service in 1978).

An articulated bogie (aka Jakob-type) is any one of a number of bogie designs that reduce weight, increase passenger comfort, and allow railway equipment to safely turn sharp corners, while reducing or eliminating the "screeching" normally associated with metal wheels rounding a bend in the rails. There are a number of such designs, and the ...
British Rail class 42 Warship, a V200 derivative B′ bogie from a Czech ČD Class 725 , showing the axle final drive gearboxes and their linking driveshaft. The B′B′ or B-B arrangement is similar, but usually applies to diesel-hydraulic locomotives rather than diesel-electrics. The axles on each bogie are coupled together mechanically ...

The original invention goes back to the Rollwagen of the Schweizer Maschinenfabrik Winterthur (Swiss Locomotive and Machine Works, Winterthur) or SLM patented in 1880.It is a simple system for light loads that found applications even when the superior Langbein system was invented in 1881 by the Maschinenfabrik Esslingen (Esslingen Engineering Works) named after Paul Langbein being the director ...
The GE CM20EMP (also known as CC206 in Indonesia) are diesel-electric locomotives owned and operated by Kereta Api Indonesia (Indonesian Railways Co.) and built by GE Transportation. The GE CM20EMPs are multipurpose locomotives, not only for hauling passenger trains (i.e. executive class, business class, or economy class), but also freight trains.
EA203 series uses air-spring bogie (bolsterless) with the TB-914 type on the train driver's cabin and the MB-514 on the middle train, which is a development of the EA201 series and Inka-Hitachi EMU, which also has a similar shape to the TR235D/TR241B/TR246E and DT50D bogie on the 203 series and 205 series which is a EMUs produced by a Japanese ...
