Annual Boiler Examination

Apologies for the delay in updating the blog - it's been a busy few week. CR 828 has accumulated about 600 miles in traffic since the end of March and is running pretty well.  In the past week she has had her annual boiler inspection. This involves the Boiler Inspector carrying out a detailed examination of the boiler in the cold condition and then returning to inspect it in steam and check the setting of the safety valves. This work was completed during the week commencing Monday 7th May and was completed on Friday 11th May. The loco also had its 28-day exam under SRC maintenance procedures.  She is now back in service again. I heard her running into Boat of Garten Station a few minutes ago while updating the blog..



A Master Craftsman at work! Mr Murray Duncan is applying the letters and numbers to the front bufferbeam.

The finished job - absolutely perfect. Thanks Murray...!

Stopped at Boat of Garten down home signal on a day when we were working a two-train service.

Days of the Diner


The second weekend of operating 828 on the Dining Train has passed successfully. She was out on April 2nd and the weather was ideal once again for her exposed footplate. So far she is settling well into this new period of operation. A small fault with the carriage warming valve was attended to during the week and she was able to provide heat to the 10:30 departure from Aviemore. After that the day was too warm for steam heating. She is using a bit more water than she should while we wait for the slide valves to wear themselves in again. Footplate crews are noticing the difference in the ride quality of an inside cylinder loco compared to the more lively ride they get on 46512. This point was well understood by JF McIntosh who was challenged once on why he refused to design outside cylinder locos when his contemporaries were proving that they were cheaper to build and easier to maintain. His view was that the inherent stability of an inside cylinder design was worth more than any improvements that could be gained by using outside cylinders....

Attending to a leaking seat on the Westinghouse Carriage Warming Valve - the radial cut across the seating surface needed removing. The circumferential cut is not a problem..

Surface plate and grinding paste taking out the defect...

Job done - radial cut eliminated and a good sealing surface achieved..

Newly cast tender tank filler cap with the old one as a pattern. All we need now is to drill the required holes in the new cap, paint it and then fit it...Thanks to SRC Engineering Director Brian Thomson for getting the casting made..

Operational...!!


At last we're back in operation...!

CR828 re-entered normal operation with the Strathspey Railway on Saturday 25th March when she handled the normal three depatures from Aviemore with a five-coach train. Then on Sunday 26th she worked the 10:30 service train and then the 13:00 dining service. She performed very well on both days and appeared to be in good mechanical condition. We have a slight issue with the Westinghouse Carriage Warming Valve and that will be investigated during the week commencing 27th March. 

The weather in Strathspey over both days was perfect. Warm sunshine and very little breeze made it a very enjoyable experience on the footplate provided the coal was kept dampened for tender first running. It was great to have two steam locos working on the Sunday and this should hopefully be a regular feature of Sunday operations throughout 2017. The Strathspey Railway is operating a new catering service in 2017 using in-house resources. Feedback on the service has been very positive. Supporters of CR828 could combine a Sunday visit to the Railway by dining in style while travelling behind the loco...!!!!

The Wakefield Displacement Lubricator. A tricky device that helps lubricate the valves and pistons. Very temperamental on Saturday 25th and performed flawlessly all day on Sunday 26th...this is it working as it should . A droplet of oil is ascending though the sight glass and will soon be on its way to steamchest..!

Together again at Aviemore. A spotless 828 hands over the service train to an immaculate 46512. After 46512 had departed at 12:30 828 moved up to the carriage shed to collect the stock for the 13:00 dining service..

Test Running.....

A lot has happened since I last updated the Blog. The loco and tender were successfully reunited by the Shed staff at Aviemore after the tender had received some adjustment to its weight distribution. A big thank you to Nathan Lightowler, Calum Titley, Tommy MacDonald and Colin Vaughan. Not only did they have to get 46512 finished and ready for a very successful Photo Charter at the beginning of March; they also had to get 828 finished off and prepared for running-in.

The loco needed some final weight adjustments before test running could commence. With this completed she was steamed and run light engine through to Boat of Garten and then on to Broomhill. She performed well and the only issue was the amount of leakage from the valve rod glands. This was attended to with help from Alan French who cast new replacement white metal packing segments using a harder grade of white metal than has been used previously. Nathan Lightowler made a new gland follower for the RH rod and reassembled both glands.

We took the loco out on a loaded test run on 17th March. She took five MK1 vehicles through to Broomhill and back and gave every indication of being fit to re-enter traffic on March 25th. The newly improved valve rod packing performed very satisfactorily. The weather was cold and damp - just the conditions when it is usually difficult to see the way ahead when running chimney first at low speed because of valve rod leakage. This time there was no difficulty so well done everyone at the Shed...

There are a couple of jobs to attend to before 25th March - the tender water level indicator has stopped working and we need to fix it. This device looks a bit like a walking stick fixed to the front of the tank. By rotating it 90 degrees water should flow into a vertical tube with small holes equally space up its length. The tank water level is indicated by the highest hole that water leaks from. Simple but effective....but not working at the moment..! Shed Foreman Colin Vaughan also wants to add a new layer of concrete to the smokebox floor to protect the steam pipe connections and the top of the cylinder block..

Wheeled At Last....

The long wait is over...! The tender wheels arrived back at Aviemore on Wednesday 8th February looking very good. They were primed, undercoated and given a top coat of gloss black within a couple of days. Other preparations for rewheeling were completed very quickly and the job was done on Saturday 11th February. Within the same day the tender was fully loaded with coal (the water tank was filled a couple of days earlier) and the completed vehicle was run over the weighbridge for axle and wheel load distribution checks. The result was very good and with a bit of redistribution the weights will be close to perfect. It won't be too long now until engine and tender are recoupled and then we can get on with some serious running-in...
