w.r.t. Weymouth boat trains, I am aware that people keep stating 74s worked to Weymouth if/when 33s unavailable but the truth is these must have been very v-e-r-y VERY rare and there are near zero recorded (or zero recorded in authoritative sources) instances of this. It is one of these urban rumours that has been inflated over time as if it was normal. Same applies to 73s re Weymouth boat train - you need a blue moon over GB at the same time as snowballs in the Belgian Congo and a pretty big failure at Bournemouth for it to happen beyond 1 or 2 cases over decades. I am not saying it never happened, just the stories are grossly exsggerated - and I ask for authoritative proof on any allegations it did occur wth a 74 (and my mates best school mate told me about it last week down the pub does not count).
I also concur. During my time on the South Western Division (1975-79) I wasn't aware of any instance when a 73 or 74 worked to or from Weymouth. In fact I very much doubt that a 600 bhp (73) or 650 bhp (74) diesel generator set would have been capable of lifting an 8 car - sometimes more in Summer - boat train up the 1 in 53 (?) gradient from Weymouth to Bincombe Tunnel.... especially on a damp morning.

Not out of the qustion for a pair to have made it, I suppose. After all, I did see a pair of 73s at Coventry on a Cross country service once.

...although they couldn't realistically haul the Weymouth boat trains beyond Bournemouth/Branksome (as
No, but they were rostered as far as Bournemouth where time was allowed for the loco changes.
Did they also turn up on ordinary Bournemouth workings (with or without the 3TC sets)?

Branksome - Weymouth wasn't electrified until 1988, and all the 74s had been withdrawn by then).

there were two Waterloo - Bournemouth etc paper/night trains that were 74s to Bournemouth - ex Waterloo 02:15 and 02:45.
The 0215 was vans only, which gives a clue as to why I remembered the 0245 (with the 3 Set)!

Regarding 73's to Weymouth Quay and 74's to Weymouth -

There is at least one recorded example of 73's working to the Quay - on 15 June 1984, 73125 and 73 138 were sent to Weymouth Quay to work the early morning up service following the failure of a 33/1 the previous night on the down service at Dorchester. Two photos of this working appear in J H Lucking's excellent book on the Weymouth Quay line.

There is also at least one recorded example of a 74 to Weymouth, on 21 August 1974 when 74003 worked an up van train - there is a photo of the working just south of Radipole Halt in the Power of the Electro-Diesels by OPC.

73's very occasionally visited Weymouth on engineering trains pre-electrification, and I am aware of at least one occasion when one worked a 4-TC in diesel mode, just prior to electrification, travelling on it from Weymouth to Dorchester - Bincombe bank was indeed a struggle!

Thank you for the tip off's. Never got to ride shotgun on any 74's but did so a number of 73's back in the distant all blue past. Slightly cramped cab once one took account of the dual controls, so 'one' had to be mindful of same if standing in the second man's position! ;)

Ta.


74s beyond Poole to Hamworthy, Blandford, Wimborne, Furzebrook and Winfrith were not unknown, and no doubt van trains to Weymouth too.

On this sort of point, 74s made it to Salisbury - I myself saw all of 74001/04/07/10 there between 1971 and 1975. And one rumoured, unconfirmed, to have got to Dinton, not seen by myself.

My comment was about 74s and boat trains. A point about a 74 is they were only 315 hp at the rail, less than 420 hp of a 73 - 2x73 840 hp is a closer to 3x74 than 2x73. Putting out 2x73 on a boat train is not only unusual in itself - it was not a location where such luxury of traction stood around on hand, 33s far more likely, so no-one noticed when the first 33 failed and merely replaced by another one.

I have had a 47 on an Up boat train, but, it was a 33 from the Quat to Tramway Jn where they changed engines - it was actually booked that day to do that, heavily amended loco and stock workings because of engineering works (actually a Sunday afternoon / evening after the works ended then putting trains back in their right places.

It does prove never say never, but then, here we are, one solitrary example so far, which still means platform end trasnpotter wibble on the subject is grossly exaggarted.

I really would not have been keen on taking a 47 down to the Quay, what with some of those curves. For that matter, how would you attach the flashing light?

I said the locos were changed at Tramway Junction.

47s were banned anyway, and only 33s permitted there.

Surprising as it might seem, those who diagram these things do actually know what is allowed and not allowed over routes.



Anyway I'm not sure it was curvature the issue on the Quay lines, but axle load. 37s were, in time, permitted.


I am pretty sure that when 03s gave way to 33s to the Quay, it was 33s only permitted, and no 73s or 74s: neither of those latter types were WQD fitted although there were other portable lamps that could have been used, same as was used on 03s.

Have to check but which came first, 74s withdrawal or 33s allowed on the Quay ? I'd suggest a 74 would be too heavy for the Quay anyway.




*** apart from that very brief period when BOMO outbased 07s were used on the ferry fuel tanks

They look like the original Mk2 variant; the toplights seem to be of four-segment, not (Mk2a-c) three.

Yep.

Bog standard SR 'ocean line express' boat train set.

van + 4 FK Mk2 + BCK + 3 SK + van

load 10, allows incoming and departing locs at Waterloo in any nominally 12 car platform

those sets were pretty much fixed formation

Have ridden shot gun on a Brush 4 out of Weymouth on a summer Saturday train back in the distant past, to take a few pics around the site of Upwey Wishing Well Halt as was during the pre electrification work. My point here being that by that point in the climb of Bincombe bank we were down to roundabout 40 mph at most. One of those banks, not extremely steep, but very long, a bit like the climb from Seaton Junction up to Honiton tunnel - very taxing after any initial rush at same with a heavy train, so for an ED to tackle same on diesel, even with one x 4 TC would have been a challenge in today's jargen!

Why would you be standing in the second mans position? there was a perfectly good seat?

Not everyone wished to sit, for reasons personal in many cases! How many drivers of 4 SUB's chose to stand as an example!

On 7 September 1977, Class 74 No. 74010 passes Surbiton on the up main with the morning Weymouth Quay - Waterloo boat train '90', which it would have taken over from Bournemouth. A Class 33/1 would have worked the train from the Quay to Bournemouth. Photo and caption Colin J Marsden

A Class 74 was a regular performer on what I think was the 7.17 from Eastleigh to Waterloo. Usually the74 was at the head of the 11TC formation, but occasionally at the rear. On at least one occasion it was sandwiched between 8TC and 3TC! There was also the occasional substitution of a Class 73.

Of course the unicorn question : Does anyone have a video of the Mighty 74 in action?

Domestic camcorders weren't available until the early-mid 1980s, several years after the last cl. 74 was withdrawn in 1977, but there might possibly be amateur or professional film footage somewhere if you're very lucky?

However, this is the preserved cl. 71 E5001 at Bournemouth in 1992 (not my video) which at least looks similar - albeit in green:

This worked a railtour from Waterloo down to Bournemouth and back icw an open day at Bournemouth depot on Sunday 13th September that year, with a small ED (73) in tow just in case!

An observation which I accept does not relate to a question raised in the OP.
I regularly visited Crewe Works around the time that they were being rebuilt - turn up at 10.30 on a Sunday, pay two bob (???) and you had a guided tour of the Works.
What I remember is that the E5000s arrived and work to dismantle them started promptly. After they had had parts and panelling removed, work seemed to be starting on re-assembly.
Something curious then happened. No progress seemed to be made for months, indeed I formed the opinion that some of the newly fitted parts had been removed again - down to just the underframe, I think I remember. - more dismantled than at the previous point when re-assembly seemed to start. . They seemed to remain in that state of suspended action for many months, the they very quickly were put together and then were outside, freshly painted.
Does anyone know if some major, unforeseen snag was encountered that held up their re-buiding? They didn't seem to last very long in service after they finally emerged; I did wonder whether a compromise was involved that turned out to be life-shortening.

May have just been the first one or two were used as a test bed to gauge the rebuild process and make sure certain components fitted correctly, and that those doing the work fully understood what they were required to do, with any adjustments being made, before rolling out the programme to the rest of the chosen locos? Any rebuilds, eg 458/0 to 458/5 were the same. The period of time allowed in the contract for the first one or two to be rebuilt was substantially longer than the main batch, and that was before any real (age related coach by coach) issues were found as each vehicle was stripped.

Thanks yes, the slow process - from memory - applied to only the first couple of locos involved so very likely the explanation.

Presumably some of this related to the issue of the body strength. When the first (E5016) was stripped down it was realised that the loco body wasn't capable of accommodating the planned changes The project then had to be reconsidered, including considerations of lengthening. In the end they managed to beef up the body strength by fitting a truss.

Thanks, sorry I missed that post. I had my memory jogged more recently down the thread.
It certainly reinforces my impression at the time of an 'oh proverbials back to the drawing board!' moment in the Works.

Its been 30 odd years since the 71 was on the metals, so whats stopping another tour? As i understand, the NRM was looking at sending E5001 to Eastleigh in 2020 for work to get it mainline ready?
