My entry into this subject really took off when in a charity shop (thrift shop) here in my small Somerset village of Winscombe I ran into Ken Harris’ ‘World Electric Locomotives’, Jane’s Publishing Co. Ltd, London 1981, ISBN 0 531 03728 2. On page 71 an Indonesian (then colonial Dutch East India) PJKA class WH (formerly ESS class 3200) is depicted and described, delivered 1924 for the 1067 mm / 3 ft 6 ins narrow Cape gauge network of the Indonesian island of Java for the 1920’s 77 mile Jakarta to Bogor electrification at 1.5 kV DC. This, also according further information, was the first Baldwin/Westinghouse licensed type of traction that the Dutch Werkspoor/Heemaf concern built, using Baldwin and Westinghouse designs and partially US fabricated equipment. Having been shifted to the sidings around the 1980’s one such locomotive still exists in serviceable condition after having been found back somewhere and having been restored to immaculate technical and exterior conditions (Internet pictures can be found, look for ESS class 3200). The traction motors and traction power controls for these locomotives and the EMU railcars came from Pennsylvania, the other equipment was constructed in The Netherlands. I learned from the Internet that at least one US Baldwin/Westinghouse electrical engineer mentioned by name was present when testing of the locomotives in Indonesia started.
It was the first indication that the Dutch post WWII class 1200 electric locomotives had a history that was rather older then what it initially appeared like. For instance, during the early 1920’s 1.5 kV main line electrification in The Netherlands itself started as well, which included conversion of the 1908 vintage 10 kV 25 Hz AC Siemens electrification of the ‘Hofplein’ line from Rotterdam via The Hague to Scheveningen beach. The order for electrical equipment for these EMU railcar trains was shared between Heemaf and Vickers Electric from the UK, of which I didn’t know until recently that they were another Westinghouse electrical equipment licensee. Hence the fact that the electrical components only marginally differed and worked perfectly well together. They both also were involved with the AC to DC conversion of the originally Siemens equipped and beautifully Jugendstil/Art Nouveau liveried EMU railcars for the Hofplein line. Vehicles of both types found a place in the Utrecht railway museum.
During the initial post WWII years The Netherlands were engaged in making good the damage the German army had caused when the tide started to run against them. A rough estimate is that two thirds of the Dutch railway network, its signalling system and its rolling stock were damaged beyond repair or had been looted and taken into the central European areas where the German army considered they could hold out against a further onslaught of the allies and the Russian army. Fortunately they were wrong on that score, but the damage inflicted was enormous and a massive amount of new equipment was required to get the nation’s railways rolling again. In 1950 the Westinghouse/Heemaf combination put in an offer for 75 electric locomotives based on the 1920’s Baldwin/Westinghouse Indonesian box-cab design, 3000 Hp 1,5 kV machines of 1Bo’Bo1′ axle configuration at NLG 700,000.- apiece. These were not appreciated by Netherlands Railways (Nederlandse Spoorwegen, NS) traction engineers because of the dated design that with a Swiss-designed type based on German pre-war electric locomotives just had led to very dis-satisfactory performance, the obsolete technical specification and the fact that the machines were not modern all-adhesion machines but had idling wheels. Werkspoor consulted with Baldwin/Westinghouse, who right that moment were engaged with the E-3 versions for the PRR. As a result a thoroughly revised machine was offered based on the PRR E-3c, albeit a full DC machine and not an AC to DC rectifier machine. Seeing that the power of the 1200 and the E-3c are the same, one could say that the 1200 is the DC part only of the E-3c, to which a resistor traction control system has been added and the transformer, tap-changer equipment and twelve ignitron rectifiers have been taken off. The price was also NLG 100,000.- apiece higher, something not appreciated by the governmental paymasters who, despite the Marshall-help offered, had to furnish the expensive US dollars for later payback. As the well-known French firm of (then) Alsthom, now Alstom, offered technically rather more advanced machines for that money, but to be paid in cheap French francs and accompanied by large French orders for vessels for the internal waterways for the Dutch shipyards, the order for US electric locomotives was cut from 75 to 25; much to the loud chagrin of Heemaf/Werkspoor and probably in their turn for Baldwin/Westinghouse who, as I understand, badly needed orders.The 1200’s, though, were looked at as solid, well-engineered and reliable machines. The main issue with them was that the weight had been cut to 108 metric tonnes (from 378,000 pounds to appr. 250.000 pounds) and that the 500 Hp per traction motor had the habit of causing unnoticed but severe and prolonged wheelslip, especially under wet conditions. Therefore wheelslip-control equipment was added in 1959, something that together with silicon solid-state instead of the ignitron rectifiers in the USA probably would have been a game-changer with much improved traction power and therewith hauling capacity of the PRR E-3 series had they been series-built. Bear in mind that the Swiss were running their Ae6/6 AC six-axle machines at 6,000 Hp for the run through Alpine areas and that German Railways were already putting four-axle electric locomotives of 5,000 Hp in service. With US axle-loads these improvements would more than double hauling power, as was much later demonstrated when the Swedish AEM7’s took over from the GG1’s. Other changes to the class 1200 machines in The Netherlands concerned the headlight configuration, the side-windows in the cabs, which were changed from the very US four-part glass-slat type to aluminium-framed two-part sliding windows that were considerably more silent and wind tight. The side-grilles were replaced by French types that let in less water.The US wasn’t cut out of other rail orders altogether, though. Most of the funds went to manufacturers as General Railway Signal for automatic half barrier equipment on grade crossings, automatic daylight colour-light signalling and NX traffic control equipment in stations and yards. Even the Dutch automatic train protection equipment (installed after the serious Harmelen collision in 1962; it’s in the book) had a US system at its basis. Incidentally, the above-mentioned Jane’s book shows Netherlands Railways electric locomotives, including the class 1200, on pages 87-89. And finally, there were Baldwin switchers of the Bo’Bo’ configuration that were license-built for NS Netherlands Railways in The Netherlands and France as NS class 22/2300, fitted with main line drop-equalizer trucks as per the Spanish electric machines, for faster mainline use.
The history of the Spanish Bo’Bo’Bo’ 3 kV DC machines is rather less clear as there is considerably less serious documentation available, neither in Spanish nor in English, whilst what’s available on the internet is far too much in the locomotive-fan corner and far to devoid of reliable technical and historical matter. The machines, built from 1960 onwards, are technically clearly based on the E-3b’s as far as the DC side is concerned and on the 1200 as far as the design of the locomotive and the DC traction-control side is concerned. Their power again is exactly that of the PRR and the Dutch loco’s. I read that they were used on the curvy and up-and-down (they had resistor brakes, see the large grilles in the roof line) coastal line in Catalonia mainly, hence that I saw one in the Vilanova i le Geltru railway museum not far South of Barcelona on that coastal line. Strangely enough they were considered heavy on the track and mainly pulled light freight trains. The latter perhaps an indication that the wheelslip-control the Dutch put in their class 1200 was not included with the Spanish class 278 and so precluded use more suited to their pedigree? Still, they too lasted a long time, in true Baldwin/Westinghouse fashion.
You might have already noticed that there are quite a few areas where more information is wanted. For instance, who were involved at Baldwin/Westinghouse with the ESS class 3200, the PRR E-3, the NS class 1200 and the RENFE class 278 programmes? What were the specifications and what was the brief? Based on what did they come with the machines they presented; for instance why did they choose the old-fashioned drop equalizer type of trucks instead of the already available low weight-transfer trucks such as the Blomberg? Why were there two types; the Bo’Bo’Bo’ and the Co’Co’? The twelve-wheel trucks are generally seen as heavy on curvy track, which makes the three four-wheel trucks a reasoned choice since no fuel-tanks under the frames were required so the space was there, but the fact that the Spanish thought that they were track munchers makes the technical side rather intriguing. I would like to find out more about that, thinking it wasn’t their wear of the track in curves but wheelslip that they had to contend with. But what did PRR think of it? Also because the Bo’Bo’Bo’ configuration went on the be very successful elsewhere in the world whilst Baldwin/Westinghouse combined four such four-wheeled trucks under the Virginian heavy coal hauling electric locomotives (another issue that requires more study in this context). So the PRR in all likelihood wasn’t disappointed for that reason. Was it PRR’s penury only that stopped the E-2/E-3 development? Keep the old machines going and at the same time gradually drop electrification in favour of the cheap diesel-electric power on offer? Why did the Virginian carry on with their electrification, in that case? But were the GE E-2 and the Baldwin-Westinghouse E-3 types considered technically worth-while, in the light of the fact that the technically quite similar GE-delivered New Haven EP-5 ‘Jet’ electrics knew rather a lot of problems with overheating due to the narrow confines of the carbody versus the heat-generating equipment installed. Their nicknames tell something about the noise their powerful ventilator-fans made when they pulled away from a stop.
Anyway, where the Dutch and Spanish think that a particular development using US electric traction technology started in the 1950’s, US people interested in rail technology at the same time see a development of electric traction coming to an end. Yet the truth is that it lived on, in The Netherlands even now a 1200 can occasionally be seen out and about and both in the Utrecht museum as well as in a rail museum in Augsburg, Germany, examples have been taken into the permanent exhibitions. Of the Spanish machines: I heard at least two are available for inspection in rail museums, among which the one I saw in Vilanova near Barcelona. Even older Baldwin box-cab electric traction can occasionally be seen in action on the isle of Java.
