My Dad, who started work as an engine cleaner on the GWR in 1930, became a driving tutor on Warships, Westerns and Hymeks at the start of the introduction of those three classes. I still have driving instructions and fault finding manuals for various sub groups of the Warships.

It is clear why there are no longer any British locomotive manufacturers left in the UK. It is not because of the lack of competent engineers but political interference. These diesel hydraulics locos in the UK were obviously retired too early due to the choice to of diesel electric. A strategy employed to try to shore up the UK suppliers. It should be noted that the final design in Germany the V218 began service mid-to late 1960s still can be seen on mainline IRE and RE services today some 60 years later. The Germans seem to know how to build railway equipment, after all the HST eventually relied on their competence.

[@countottovanshanoo822]

Whilst a fan of the hydraulics, their early demise was due in a large part to lack of ETH ("non standard"), often overlooked.

[@chrislaarman7532]

Not only the class 218 is still in use in Germany. Several class 220 (original V200) are in use with private operators, and even most of the class 221 (upgraded version of the V200) that had been recovered from Greece have been refurbished and put into service by the privates (like track maintenance companies). There is at least one video (trailer of a DVD) of this refurbishment here on KZbin ("The Train TV" channel, I think, in German).

[@drstrangelove4998]

Sadly true.

[@pizzaplanettruck9761]

One additional fact worth mentioning is that a diesel-hydraulic, Class 52 No. D1015 "Western Champion", got to pull the funeral train of Winston Churchill on the return trip. This, together with the Western Farewell, saved five of the seven preserved Westerns.

[@Rog5446]

The Hymeks were certainly the best performers, despite being of a lower power output. To put it bluntly, they were put on workings that required a more powerful unit and thrashed. However, they took the thrashings and delivered a performance that could only be expected of a Western class.

[@johnnyrvf]

Between 1968 and 1974 I went to boarding school in Bideford, N. Devon. I remember some of the named Western class locomotives pulling the trains to and from Exeter from Paddington at the beginning and end of each miserable term. Oh such happy memories of my childhood and teens!

[@ed_menno]

The Modernisation Plan was not ill conceived. It came at a time of great change technological innovation. Long established norms were being ripped up and a whole new world of opportunity was out there - locos that didn't need turntables, could be started at the touch of a button, and huge competition from road and bus and eventually from air. The plan tested and challenged the capabilities of British industry when Britain was broke and in decline. Although many of the locomotives designed and built were not up to the job, lessons were learned in the process. You mention the Class 20 which saw 50 years service, ditto the Class 47s. The 37s are still going. The Class 08. The AL1-AL5 electrics were the testbeds that gave us the incredible Class 86s, 87s and 90s - note that (as far as i am aware) we never imported an electric locomotive until the class 88 in 2016. Sure in hindsight things could have been done better, but if i was told the future is not the norm and all i have was a blank canvas and nothing to paint, i'd ask a number of creative people to paint that future.

[@daniellewis1789]

Yes, but they didn't have the funds to do so.

[@andrewdarley8988]

@@daniellewis1789 Exactly so. In fact when they started designing the British Rail standard steam classes the concept was that they would last for 20 years plus until all the main lines could be electrified. Then when the modernisation plan was finally released it was decided that they would have to be phased out quicker than that. This meant that some of the best steam locomotives we have had only saw a life of about 10 years then further waste from the Ill conceived scatter gun approach buying huge numbers of different deisel locomotives, most of which fell by the wayside.

[@muir8009]

​@@andrewdarley8988 it even sounds the "plan" for electrification was really on a nearly ad lib basis. Gerard Fiennes sounds like his big push for a fleet of deltics was because it was late in the pilot scheme era that it was learnt the East Coast wasn't to be electrified. DP1 of course being tested by both East Coast and West Coast, but nothing became of it until the non-electricification necessitated the push for squadron production. Most intriguingly, I think I've just repeated myself by altering some words with no reason whatsoever...

100,000 subscribers is excellent congratulations! In the US🇺🇸 Southern Pacific’s diesel hydraulic experiment yielded generally higher maintenance costs. They did, however, produce higher tractive effort versus conventional diesel electrics- but at the cost of higher maintenance costs.

[@BuckeyeNationRailroader]

It was much more than that. Simply put the Diesel Hydraulics were not cut out for the North American Railroad work environment. Locomotives in the US are often notorious for working long hours on runs that sometimes take two to three days and travel up to over 2000 miles. The Hydraulics simply were not expected or built for this kind of work environment, and nowhere in Europe was this ever replicated. In addition to that the Diesel Hydraulic Engines that were used had more intricate moving parts increased the maintenance costs, and the different transmission system basically made them unable to be worked on in the North American railroad work environment at the time. Not only that, but the Diesel Hydraulics were proven to notoriously HATE going through Tunnels, getting so hot to the point the valvetrains often melted. It was ultimately these flaws that doomed the Hydraulic experiment in the United States, but it wouldn't be until the 1980s that the Diesel Electric was able to meet with the Hydraulics Power.

[@cmdrflake]

SP assigned the hydraulics to the Central Valley out of Stockton and Bakersfield where they did relatively well. They still disappointed SP with their extra operating costs even on the DH640’s from ALCO.

[@BuckeyeNationRailroader]

@cmdrflake They worked other parts of the system other thank just Bakersfield and Stockton, and even here they were not really that cut out for the North American Railroad work environment. By the time the German company was able to sort out the flaws of what the units were having, GE, EMD, and ALCO caught on to what the SP was wanting and so they offered a locomotive with none of the drawbacks of the Hydraulics. Simply put if you have ever heard of the Southern Pacific and Rio Grandes famous "Tunnel Motors" these are what essentially doomed the Hydraulic Experiment in the US

I appreciate that there are a lot of enthusiastic people that admire this type of loco but in the cab doing 90 mph they were not a good ride

[@anthonystevens8683]

Another brilliantly narrated and educational video Ruairdh. Once again the short sighted along with the non joined up strategy of BR for the future post steam power. A shame as some of the hydraulic diesels has arguably a great personality compared with the box designs of many. I do appreciate the decisions made in the end but as you mention these classed seemed doomed prior to construction. Many thanks for sharing.

Congratulations on 100k Subscribers! Well deserved.

[@chrislaarman7532]

Me too: congratulations on reaching 100k subscribers, and thank you for the effort and sharing! :-) It seems to me that railway companies develop a preference for "electric or hydraulic (or even mechanic)" transmissions with diesel vehicles, and (back then) "single or compound" working cylinders with steam locomotives. However, as passenger services seem to grow into multiple-units, locomotives will become more of a goods-only traction power, likely to be ordered by major operators and rent firms, forcing the markets into off-the-shelf traction. Just think of the ubiquitous Class 66. And of hybrids with diesel for the "last mile", making diesel-electric the obvious choice.

[@johnkeepin7527]

A couple of other historic items related to the withdrawal of two of them. The Warships were not fitted with train twin pipe air brakes (perhaps due to the tight fit for various things), so they were not compatible with modern rolling stock into the 1970s. The Westerns were not fitted with electric train heating (ETH), so fell out of use when air con stock, i.e. Mk2d/e/f came into service on the Western Region. Class 47s (some of which had ETH added) came into use on the South Wales services in lieu of the Westerns from the early 1970s.

Its also worth noting that orders for the Hydraulic classes were done in full before the pilot locomotives and their teething problems could be rectified so instead of one locomotive being taken out of service it's the whole fleet,and the maintenance facilities weren't up to standard and BR,s cost cutting didn't help either

It’s easy to criticise the development of so many different locomotive types in the 50s but just like the civil and military aircraft industry there were many established designers / manufacturers and technologies to use and it was tempting and practical to get them to produce models suited to a particular role or region. In the end there was mass conglomeration and standardisation and with aircraft we ended up with just DC-9s, A320s and 737s instead of BAC 1-111s, Tridents, Mercures, Viscounts, Vanguards, Elizabethans, Yorks, Hermes, Comets, Caravelles, …..

@@Hattonbank the actual blue took 2days, but the preparation took 2 weeks, after sanding down the blue we found pockets of water behind 8mm thick filler over the stressed steel skin, that all came off, steel treated and re filled a big job. After 2 undercoats and flatting back the top coat went on. BR or rail blue paint was developed with Williamson's, to be hot sprayed, it's a very thick paint, so the heated paint or heated spray guns makes the paint runny enough to spray. The idea was thick paint wasn't designed to be varnished, so taking out an additional task. Also when the loco (and the BR carriage sets) went through the washing plants, the brushes would take off a thin layer of paint revealing a new bright colour beneath. Anyway, we didn't have that ability, so to make the paint flow, we used a little boiled linseed oil to keep the wet edge going, for the final coat we did add some varnish for a glossier finish. Hard work, made it up as we went along using our 30 years experience. Hope this helps.

Hydraulic transmission in lightweight bodies and under-frames made sense to wr operators faced with the lumbering A1A prototypes. Just a shame that we didn't have the engine experience needed to build our own suitable power plants and had to import German engines that were developments of Zeppelin engines! They were built under licence by Armstrong Siddely in Coventry (very badly bombed ten years or so earlier)! I worked at the factory that made them and lightweight high speed diesels were uncommon at the time. Think if the public knew of the money spent on licencing a German product there would have been an outcry. On a still and clear night you could hear a Western spooling up its turbos from miles away as it thrashed up to Paddington making up time. As an engineer you guessed at the temperatures and feared for piston rings and valves.
