June Progress

Posted on July 1, 2017. Filed under: Monthly progress |

The last south passenger train of the day calls at Culrain about seven fifteen in the evening. The Restaurant Car, which earlier in the day travelled north to Helmsdale with the HR TPO, now returns to Inverness. The TPO will return the following morning.

Train 19.15 Mid 1950s 170628 4519      Evening departure for Inverness

The newly applied lion-on-wheel symbol is just visible on the fully welded Stanier tender of 45473, which corresponds with the time period of the red and cream coaches, while the full brake behind the engine is in non-passenger coaching stock livery. The part welded Stanier tender, awaiting the building of a second Black Five, sports the later large BR totem to allow a change of time period to maroon coaches.

At the beginning of the month I learned a very important lesson during a visit to see the large, EM gauge South Pelaw & Stella Gill Flatts layout in Middlesbrough: it takes a determined and concentrated period of check/correct/review to prepare a layout for exhibition. The 20’ x 30’ South Pelaw is housed for 3 months in a large, open-plan area of an office building. It’s not planned to be exhibited for another year, a good clue for Kyle of Sutherland.

Kyle of Sutherland is currently going through a similar process in its 15’ home-based configuration with 2’6” cassette tables at either end, rather than 5’ exhibition tables. The train lengths may be restricted, but what a lot I’ve learned and applied. There’s hardly no aspect of the scenery, electrics, track, cassettes and rolling stock that hasn’t needed some sorting out.

Early successes include the LMS D1720 coach Sc6735M, which used to repeatedly derail near the south entry point to the passing loop. I blamed the MJT torsion bogie gummed up with paint, preventing it rocking smoothly. Not so: the culprits were the cosmetic side frames catching on the solebars on the point’s curves. The temporary cure was to raise the height of the bogie by the thickness of one washer. In the longer term, I will look more closely at the depth and position of the side frames. I suspect some other coaches could exhibit the same problem. All rolling stock is currently going through a programme of checking the back-to-back and overall weight.

I’ve been testing 54458 and 54495 on their return from the paint shop. In the final stage of modelling I removed their motors and worm drives while leaving the High Level gear boxes in place. This has allowed me to push and pull them around the layout with a small diesel shunter to check their running. Out of interest the shunter has over-scale, “easy couplers” at either end, which get round the problem of using the very fiddly scale couplings on Kyle of Sutherland’s rolling stock. Well, I found out more than I bargained for: the steps of both locos fouled several feet of the Up platform. The solution with 54458 was a combination of cutting back the wooden platform edging and supporting joists and bending back the steps. I’m not happy with the latter part of the remedy as it noticeably alters the appearance. I had the same difficulty with the bogie steps of the HR TPO and in this case I reduced the width of the step treads, which looks better. I’ll mull things over before addressing 54495. Even though the two locos only weigh about 90 gm without motor, tender and any added weight, they ran very smoothly throughout the layout and I may simply keep oiling and running them in this way for a while before replacing the motors.

The 10 train exhibition sequence planned for the layout involves uncoupling engines, turning and replacing them at the other end of the train. I’m minded to install easy couplers at the rear of all locos. As a result of this concentrated period of operation I’ve come up with some further ideas to improve the layout’s “ease of use” for other operators. There are also some train movements precluded by the design of the layout’s electrics. That’s more to think about.

I now understand the benefit of having a comprehensive set of specifications for all aspects of the layout and its stock. I’ve taken particular notice of the standards employed on St Merryn, the P4 exhibition layout built by the South London Area Group of the Scalefour Society. I’m constantly surprised how even the smallest departures from standard can cause derailments in P4.

All this confirms I’ve put loco building on the back burner. I’m first going to concentrate on proving, and maybe improving, the layout with my current stock of five steam and two diesel locos.
