1943 Livery WD Austerity 2-8-0 On loan to the LNER, based on Bachmann's recent post war model.

 

A WD aimed at the June 1944 tank trains on our extended "Little Histon" layout.

Newly arrived from Rails of Sheffield

 

Our application for the new WD:

This WD will portray one of the (then recently built) 350 Riddles designed war department locos temporarily loaned to the LNER before virtually all 900 plus WDs were shipped abroad for duty with the Army Transportation units in late 1944 and 1945.

However, as received, Bachmann's current offering has livery and markings that reflect a later period soon after the locomotives returned to the UK after completing their service abroad in circa 1946. So the first task is to research the livery and numbering arrangements of our target mid 1944 period locomotives.

 

 

A bit of livery history:

The WD 2-8-0s were produced at the two North British Locomotive factories in Glasgow and The Vulcan Foundry plant in Newton le Willows, with first deliveries appearing in 1943. The locomotives were initially out-shopped with a black and khaki brown paint scheme. There are very few photographs on the web that show the locomotives in this scheme and the two we have found show rather different distribution of the colours. From the end of March 1944, the livery was changed to black and khaki drab, which is a pale green hue. It is thought that the locomotives may all have been repainted in the new green colour when their original 4 digit numbers were all pre-fixed by the number 7, immediately before they left for service abroad.

 

Copies of the only two khaki brown livery photos, showing much more black used on the lower photo.

 

Original 3 but mainly 4 digit numbers appeared on the cab sides in golden yellow. Initially as very small circa 2 inch digits, but later in increased sizes up to 8 inch. The tenders received "WD" letters and later, with the war department arrow motif in between.

We have yet to identify specific numbers for the 350 locos loaned to the LNER during 1043/44. However, the choice of a black and khaki brown paint scheme should give a much greater choice of possible locomotives as this appears to have been used from early 1943 to March 1944.

Two photos of obsolete past Bachmann models of the WD 2-8-0. Although the sand coloured loco looks similar to the North British photo at the top of this section, its difficult to believe that such a colour scheme was intended for use in Western Europe, so our scheme is based on the second B & W photo from the top, but uses a slightly darker shade of Khaki.

 

The 1943 livery:

I've brush painted the khaki on to the relevant parts of the boiler, cab and tender. I began with Humbrol 26 "Khaki drill" matt enamel, but then switched over to 29 "Dark Earth" to obtain a very slightly darker shade. I've now noticed that the photograph indicates a need for some additional painted areas at the cab entrance on both tender and loco, so I'll tackle that pending the number choice. 

 

Just need to decide upon the number and apply that and some WD lettering, followed by some light weathering

 

Davidís Info on the Wartime WD 2-8-0 numbers

The Bachmann model of 77003 which was built 2/43 by the North British Loco Co in Glasgow from there Hyde Park factory, Order Number L943. It was one of 50 locoís which were numbered 7000 to 7049. All of this batch were lent to the LNER in early 1943 apart from 7011,15,42-49. Of those which were lent to the LNER some were based at Peterborough, New England yard including 7006-10, 12, 19-22, 29,30,35-8 which may have worked through Histon.

However, the North British Loco Co also built 300 (also Order Number L943) locoís numbered 7150 -7449 from May 1943 to March 1944. Of these locomotives the following were allocated to March, which I think are a better bet for working the tank train.

Iíve selected 7350 as the primary candidate as references suggest that numbers in this group are most likely to use 8 inch high cab numbering (which I have available).

 

Original Number 7350 now in place, also with WD tender side markings.

 

 

 

Another Chinese slip-up:

When I removed the upper body shell from the chassis to access the RF suppression capacitors, for removal (as these are not needed when the motor is powered from a DCC decoder) I discovered an assembly error.

The worm gear on the end of the motor shaft, drives a vertical gear chain which terminates in the driving wheel axle cog. However, on this locomotive, the gear wheel directly driven by the worm was only just meshing with the following gear, as it was offset to one side. A quick look at the assembly drawing confirmed that the gear wheel and its adjacent spacer washer, had been assembled in reverse order. I managed to extract the gear wheel shaft and re-assembled the pats in the correct manner.

The problem parts after re-assembly the correct way around

(before I removed the motor supply coils and capacitors, visible on the top).

 

Decoder, speaker and stay alive capacitor arrangements:

The 1950s WD austerity locomotive solution works well, so this will be duplicated.... except the Westinghouse pump sound effect needs adding for the war time period. Digitrains kindly requested a new revision of the WD sound project, including the pump sound from the originator of the sound project, Mr Chetter. 

In fact the revised WD 2-8-0 sound project also includes a new offering of an additional engine chuff running sound set. These can be selected via the DCC controller to simulate different reverser settings and their resultant steam cut-off effect on the chuff sounds.

To be able to select more than two sound sets, version 37 (or higher) of the decoder firmware seems to be required but unfortunately, as received, the decoder was equipped with version 36. However version 37 is now available from the Zimo website, so I was able to load it and make full use of the new functionality. 

The locomotive is now running well, with the Westinghouse pump sound also now added to the randomly timed background sounds.

Finally, a little additional weathering to the tender and cab sides. (That coal dust gets everywhere!)

 

Running Characteristics:

This WD is a really smooth runner without any need to fine tune the Zimo BEMF control CVs. Its slow speed performance in the forward direction, with 4 Hattons Warwells and a couple of vans, is really exceptional. I've hooked up 8 heavy Hattons Warwells, a couple of ammunition vans and the brake van on the loft layout and I'll give it a run when I next get the opportunity. If successful I'll make a short video to show the train in action...... No problem hauling the longer heavier train...... video link is now below!
