August Update

Thanks to all those who came along to support 6940 running over the 60’s weekend. Another 150 miles or so in the bag with the old girl soldiering on. One trip was completed to Friday 6th to support a wedding train as steam working was suspended and then 3 trip diagrams were completed for 60’s weekend each day. The weekend saw two new traincrew to our roster, me passing out as driver and George Walker as second man. Well done to George and thanks to everyone who has supported me over the 12 years I have been involved with the Group.

6940 continues to be rostered for all future running as our only loco in traffic.

D5310 unfortunately appears to have sustained a failed No 2 traction motor bearing after developing bogie problems on 7th July. We need to conduct some more investigation work, but the nature of the damage to the commutator would suggest the armature has dropped onto the bottom set of brush gear. If this is indeed the case, the loco will require a lift, bogie strip and motor repair. We are looking at all options for this but if you can assist with technical advice, have a spare motor to sell or can assist with portable lifting jacks we would love to hear from you!

We will be looking at 1566 in the next couple of weeks with the aim of trying to tighten the cylinder heads to see if that cures the leaks. If this is successful then the 47 may be back in traffic before the end of the season.

We are also looking for a visiting loco for our diesel weekend on 29th/30th September and our “Along Cambrian Lines” gala on 12th & 14th of October. If you’re a loco owner or owning group member reading this and are interested please get in touch. We’ve got an amazing line to sample!

Finally, here’s a photo of 6940 at Carrog on Sunday afternoon under the continuously blue sky we are becoming increasingly used to. Some rain would however be very much welcomed, with the wild fire on the Llantysilio mountain above the valley still flaring up after over two weeks of burning. Our thoughts are with the local fire crews who continue to work around the clock to keep it under control.

Classic Transport Weekend

Classic Transport Weekend on 30th June and 1st July will see 6940 working 3 return trips on both days – 10, 12:15 and 14:30 ex-Llan trains.

Over 100 vintage cars, buses and lorries on display at Glyndyfrdwy, with free bus rides. One steam loco and a DMU also in use each day. Lots to see along with the usual array of superb cakes, pies and ales at the line’s eateries. Cambrian Real Ale Bar should be open at Glyndyfrdwy too.

Sunday 17th June – D5310

This Sunday’s running day will be handled by D5310 in place of 1566, which has unfortunately been declared unfit for traffic due to injector problems and the development of new water leaks on the power unit.

D5310 should then (finally!) head undercover later this month for repainting.

Looking ahead to Classic Transport Weekend on 30th June and 1st of July it is expected that 6940 will work the 3 Llan-Corwen return trip diesel diagram on both days. The 37 performed well on the 9th of June running day following replacement of the fan clutch and repairs to a blocked and leaking air pipe under No 2 end cab. She is seen below at Carrog carrying a well-travelled charity memorial headboard brought along by one of our passengers.

Spring Update – 6940 for June 9th

Sorry it’s continued to be a bit quiet on here of late. A big thanks to those who came along to support our running at the Western Changeover Gala last month. The event proved a challenge for us, with both 6940 and 1566 suffering failures. 1566 was quickly remedied thanks to a late night repair of a coolant hose and back in traffic for the Saturday and Sunday of the 3 day event. 6940 was also repaired with a suspect control circuit breaker but unfortunately failed again on the Saturday, so was replaced with D5310 making for a rather pleasant “Sulzer Sunday”.

6940’s failures were traced to the breakdown of the coil in the electromagnetic fan clutch. A replacement was sourced, fitted and successfully tested last week. This wasn’t the easiest or cheapest of jobs but Mark Smales managed to fashion an excellent tool for removal of the clutch and Unipart Rail remarkably still had a clutch on the shelf! 6940 should now be fit for our 9th of June running day and 10th June driver experience, pending a test run in the next week or so.


1566 completed her 22nd April running day successfully but there were a few issues that came to light that require attention. We will confirm if she is fit for her 16th June running day in due course.

D5310 continues to be available but we plan to withdraw her for repainting as a matter of priority and as soon as we can get her under cover in order to replace cab window seals and attend to some minor bodywork corrosion.

Loco allocations for Classic Transport weekend in July and 1960’s weekend in August will be confirmed in due course.

Western Changeover Gala & 22nd April Running Day

The timetable for the upcoming mixed-traffic gala is below. 6940 will work the D1 diagram and 1566 D2 on all 3 days.
 Both locos work a freight trip between Goods Junction and Carrog each day.

Traction for our 22nd April running day will be 1566.

There has been plenty going on in the Group over the last few months. D5310 has seen regular use on lineside clearance trains and also worked during the Easter weekend, drawing back trains from Carrog which utilised the suburban rake, which has had a beautifully restored 4th coach added. The 26 has benefitted from a coolant change, which proved a wise move given the repeated cold spells.

A more detailed news update will be provided soon but in the meantime our Facebook page is well worth a look for those with FB accounts. It’s updated regularly and packed with photos.

A successful Diesel Weekend and a big thank you!

A massive thanks to everyone who supported our Diesel Weekend. We were so pleased to see so many visitors give there were large events on elsewhere. Thanks also go to the staff and volunteers who were involved in making it happen. In particular we all appreciate the effort that Pete Edwards put into planning and organising the event and the thousand odd hours that Mark Smales has invested in getting 1566 (and 6940) fit for the event.

1566 unfortunately failed at Berwyn on Saturday evening due to an oil leak. This was a big disappointment for us all and we’re sorry she held the last trains up. She was rescued by 08195, delaying the train by an about an hour, but getting everyone home and offering some rare mainline rod haulage! D5310 worked the evening trains in place of the 47 and this was also not without incident, when acrid-smelling smoke started to pour out from under No 1 end as the train approached Glyndyfrdwy. We feared the worst and suspected a traction motor problem but, after a thorough inspection and motor isolation, nothing untoward could be found. She then went on to run flawlessly for the rest of the evening and on Sunday. We’re at a bit of a loss as to what happened but wonder if a plastic bag blew up and became stuck against the warm brake blocks – one also got stuck to the front end of 1566 on Sunday (without the smoke though thankfully).

08195 to the rescue of a temporarily stricken 1566 on Saturday evening.

In true LDG spirit, Mark pulled us all together early on Sunday morning to get 1566 sorted and she then ran well on Sunday, completing her first full day in traffic for over 5 years. This was also the first time we have fielded 3 of our own locos for 6 nearly years. The oil leak was simply a lose union on a pipe that fed the rocker gear on top of the block, but was a difficult one to see and fix whilst the loco was warm and running. By the time we’d found and staunched it we had lost so much oil that the low pressure sensor kicked in and this was made worse at Berwyn due to the gradient causing the oil to run away from the pick up pipe. A repair was also made to another leak that developed from a corroded pipe on the hydrostatic oil system that feeds the coolant louvres and fans. 1566 still needs some other issues attending to. This includes an outstanding minor water leak on the block which we can’t quite see the origin of and, as a number of people commented on over the weekend, still being low on power. Although the turbo seems to be working OK, the engine is not receiving much charge air pressure, so is not loading up fully. This will be investigated over winter but the loco can still work trains at Llangollen with more than enough power in reserve!

D5310 looked the part with her new full yellow ends, especially when hauling or lined up with her BRCW stablemate Class 104 DMU, which looked and sounded superb all weekend.

The brake van trips were a big hit. Matt Davies and Pete Edwards put a lot of careful planning into these behind the scenes, meaning they could offer some pretty impressive rare track for travellers, including river sidings, the diesel road in the yard and the headshunt at Llangollen. We appreciate the support of Kev Adlam and the members of the Branch Line Society/PLEG for getting together a large number of advanced bookings that made putting these trains on all the more worthwhile.

Here’s hoping this lays the foundations for another successful diesel weekend next year. The provisional date set is the 29th & 30th of September 2018. Thanks again Folks!

Here is the timetable for this weekend’s event.  Sorry it’s so late, we’ve had some challenges around crew availability that threw us a very tightly curved ball at the end of last week. Not an easy job!


The DMU will be the Class 104. 08195 will haul the brakevan trips to the throat of Pentrefelin yard. All 3 locos are ready for the weekend and final preparations begun last night -the photo below shows all 3 locos at River Sidings. D5310 and 1566 were run up and tested, 6940 has received repairs to some corrosion-related air leaks and a new section of cab floor.

Some BR-era nostalgia and might-have-beens will be gracing coach droplights and the evening trains will see Travellers Fare partially dug-up from the corporate branding graveyard.

The group are very much looking forward to our first full diesel event for 3 years and look forward to seeing you there.

With a busy July of running now complete, it’s time to start looking forward to our season finale in September.

We will have a B timetable running day on Saturday 9th of September, traction will be D5310.

It’s then all hands to the fuel pump for our Diesel Weekend on Saturday 23rd & Sunday 24th September. This will include the full public debut of Class 47 1566 in BR Blue, working her first full day in traffic for over 5 years.

We are busy putting the final touches to the timetable but can confirm planned attractions are:

Traction: D5310, 6940 & the return of a very shiny BR blue 1566. 08195 is pencilled-in for shunter shuttles and a Sunday morning PLEG charter.
DMU: The ever-loud Class 104

5″ gauge miniature railway on platform 2 at Llangollen courtesy of WDSME. Traction should be a 27 and 47. New track and traction red pens at the ready!

A beer train should run on Saturday evening.

The timetable should be available soon and will hopefully include some proper length trains and a DMU drag. Please note all locos, workings and attractions are subject to the usual caveats of availability, operational constraints and b*sterd bad luck. Your understanding is much appreciated as it’s a while since we’ve done an event like this!

1960’s Weekend – Two Locos Out

Thanks to all who came along for a ride-out at our 8th (and currently final in its current guise with Diesel Group members as organisers) 1960’s Weekend. Due to a shortage of steam locos, we ended up with a request for both D5310 and 6940 to be in use on both days. Although confident, this would be OK, as usual it ended up being a challenge!

2 of 6940’s bogie brake cylinder seals needed urgent replacement before the event. They had been passing air for a while but failed completely when the loco was used for shunting just over a week before the event. Hasty enquiries resulted in a supplier in Sheffield being able to assist us, although it was a close run thing – they arrived at 15:30 on the day before the event. Fortunately they fitted like a dream and did the job perfectly. We just gained a few less/grey/both hairs in the process! She is seen below running round at Llangollen on Sunday 23rd.

D5310 had air problems of her own when she was used on the Tuesday before the event to shunt at Glyndyfrdwy. Both the brake feed cut off and train brake valve at No 1 end began passing air badly. Both were removed, stripped and cleaned on the Friday before the event. Fortunately we had a good turn out of working members for this day and, despite it being very last minute and working in the most awful rainy conditions, both locos passed FTR at around 4pm and then headed straight into shunting work to prepare stock for the event. She is seen below getting the ECS to River Sidings underway on the evening of Sunday 23rd July. Doesn’t she look the part on those subs!

After all this very damp drama, the weekend itself went largely without a hitch. This was the first time we have fielded two fleet members on the same day for nearly 4 years – the last time being the September 2013 Diesel Day. It was a great sight to see our locos crossing one another on service trains, as George Walker’s photo below shows occurring at Glyndyfrdwy, also on Sunday 23rd:

After a busy July, it’s now time to look forward to our Diesel Weekend on September 23rd & 24th. We are confident of being able to field D5310, 6940 & 1566 and a railcar. We are planning interesting workings, a miniature railway and an evening beer train. More details will be provided soon – keep checking back.
