So, after the successful steamtests and an inauguration down in Llechfan Garden Railway as is the tradition for three of my four locos, it was time to start tinkering and upgrading the Bertie. Less than two weeks ownership, and it was in pieces....



You can see the still uncluttered makeup of the cab, and the top boiler blanking plug as of yet untouched. Roundhouse supply a special thick box spanner with the kit, also with holes drilled to provide a lever in as they are on severely stiff. So, bodywork lifts off with two small nuts removed - one under the removable safety valve done, the other in the back of the cab followed by the removal of the gasjet through the square rear cab hole - unscrew the union nut between gaspipe and jet, undo the holding bolt and voila, gasjet removable. Wiggle off the body and you're now at this stage:-



~~~~~~~~~~~~~

After a two hour operation - readin instructions very carefully and being a little stuck regards aligning the top and bottom turrets of the water gauge glass [discovering that their pipes may need to be bent slightly to make them align just about upright, but so that the glass will slide in easily and hold, without risk of breaking].



Water gauge glass done, it was time to install the new water topup turret...



Simple - screw off the topholding bolt, remove the holding plug, undo the steampipe-to-regulator union nut, remove old basic turret with regulator on. Unscrew regulator and it two nuts and glands, attach to new turret. Screw on the water feed pipe to the other thread on the new turret - tightly - and then attach the now two-ended turret back onto the steam system.



Here is a clearer view of the new turret on the steam system. You will also see that at this juncture I finally added the pressure gauge. With that, voila. Cab and control upgrades all finished:



BEWARE: When reattaching the regulator to the new turret, the second union nut on the regulator piece with the thick black o-ring that the needle turns through, to enter the turret section is tricky. Tighten it just enough so that steam does not escape but do not tighten it until it it immovable or overtight. I did this and found that my regulator control suffered.

Bertie regulators are such that just a small touch, say 30 degrees, will admit enough steam to get a scale slow speed crawl. 60 degrees will get a more lively pace and 90 degrees is over too fast. In optimal conditions.

However by over-tightening as described about, my loco suddenly became very heavy on regulator, not having much scale between 0 and 75 degrees, then at 75 degrees admitting enough steam to trot about at a lively pace before going into the too-fast speed levels. Once we loosened this one gland nut, the loco's legendary responsiveness was restored.

As a result, once this re-tweak was carried out after some advice, a very successful afternoon was had last week on my week off at the Barley it Railway and Works. More on that later....needless to say, the loco went under quite some rigouous testing.

Thanks Stoker -- this engine is pretty fantastic, having already proven itself on three lines already

Now just need to name him...

Looking good, Douglas! Still be a while till it's properly run in I guess.

Hmm... Cadno, Vixen, and now Fennec...

Do you like foxes by any chance?  

Take a look at this picture:



See anything unusual?





Here's a close-up of the cheeky bounder:

Hi SLR,

However did you guess? My first proper loco buy, a maroon Accy Leader almost got named Kitsune.

Nice photos there - you must be a fox friendly garden if the little fuzz can feel safe to have a nap there

I expected you to work her up

But what are you doing beneath that tree?

The slide bars & crossheads are non-functional on these Roundhouse locos, but the twin slide bar option does look good nonetheless.

I would not bother spending money on the non-functional combination levers. I've had fouling issues with my Katie & Alco's combination levers, and Peter Angus told me last year that he had stopped fitting them to his locomotives for the same reason.

Roundhouse recommend putting some motor oil between the gland nut & regulator arm to keep the regulator working freely.
