HO Review Bowser GMDD SD40 2 CP 6046
 |
| The latest addition to my roster, CP SD40-2 #6046, is almost ready for service on the layout. A bit of weathering will complete an exquisite HO model. |
At the Ancaster train show this past weekend, I had the opportunity to pick up one of the new Bowser General Motors Diesel Division (GMD) SD40-2’s, part of their recent release of units matching prototypes purchased by CP, ONT, and BC Rail. I must admit, this was one of my most-anticipated purchases, and I’m glad the wait is finally over! This is not intended to be a 100% complete review, as I may miss a few things, but it should capture most of the locomotive’s highlights.
The Prototype
In 1:1 scale, CP 6046 is a GMD-built SD40-2, rolled out of the London, ON plant in March 1983. Part of CP’s second-to-last order for conventional SD40-2’s (the SD40-2F “Red Barns” followed in 1988), the unit was delivered in the road’s Action Red paint scheme with a small multi-mark adorning the rear of the long hood. Customary of late CP SD40-2’s, CP 6046 is equipped with features including the late-style corrugated radiators, Q-fans (at radiator), external radiator piping, anti-climber on front pilot, and angular traction motor blower duct. Over the years, the unit has undergone minor changes to it’s appearance, most notably a repaint to the solid red Action red paint scheme, as well as the addition of ditch lights on the front pilot. More information can be found HERE.

| CP 6049, three numbers away from the my Bowser model, is from the same 1983 build as #6046 and is in the same paint scheme. Remarkably intact after 28 years of service, some updates to its' appearance include frame reflective stripes on the side sill, replacement handbrake wheel and battery box door, new snowplow, removal of the class lights, and weathering which includes some fading, darkening of radiator/dynamic brake/air filter screens and burnt "CP Rail" on the side of the hood.

When Bowser first announced the release of an HO GMD SD40-2 specific for CP, I immediately set aside some of my hobby budget specifically for this unit. I had modelled two CP SD40-2’s in the past (and one of them is almost done by now…) and one thing I realized in researching the required detail parts was the myriad of possible detail configurations on CP’s SD40-2’s. Differences exist in nose length, radiator type, fan type, winterization hatch, snowplow, horn location, radio antennas, front pilot (anti-climber or not), traction motor blower duct, and last but not least, paint scheme. So when I opened the box and took the model out, to say that I was impressed is putting it mildly – from an initial inspection, I was blown away by the level of detail that Bowser put into the locomotive. The first thing I noticed was that the engine was screwed into a plastic base as part of the clam-shell style of restraint in the box; I like this method and think it offers better protection than simply clamping against the top and bottom of the locomotive. A small piece of brake line did separate from the model (I have yet to determine exactly where it belongs), but that’s perhaps not unexpected when the engine has already travelled half way around the world from the factory. I could say that “the model closely matches prototype dimensions”, but since it is already obvious that it does. Instead, I’ll go over some of the more impressive details that Bowser put into the locomotive.

| A close-up shot of the cab shows details such as class lights, air hose glad hand detail, builder's plate, and handrail detail. |
- The Dofasco name on the truck sideframes – some might consider this an insignificant detail since it’s usually buried under years of road grime, but I thought this was a really neat feature, one of the things that makes it distinctly Canadian.
- The Canadian-style handrails – Many times it is forgotten that the handrails on GMD SD40-2’s is somewhat different than those built at La Grange. Since CP SD40-2’s feature unique upright stairs (to prevent snow accumulation in winter), the handrails follow suit by following a more vertical profile at each corner than US-built SD40-2’s. Likewise, a unique CP add-on are the chain attachment triangular hoops on either end of the engine. This could have easily been overlooked, but again are a signature detail on this model.
- The Class Lights – not only does the model look nice, but it is detailed inside and out. A great deal of effort went into the electronics on the locomotive (especially sound units equipped with LokSound decoders), one of the most interesting details being the individual white, red, and green LED class lights. I’m glad I didn’t have to solder any of those wires!
- The other lights – a number of minute LED’s provide impressively bright lighting on the engine. One thing I was impressed by was that the LED’s for the ditch lights are mounted in the shell, right on the pilot, not lit by “light tubes” or “fiber optics” as some other manufacturers have done. This means that the ditch lights are just as bright as the headlights, not much dimmer as on other models equipped with lit ditch lights.
- The Graphics – not only is the model detailed correctly, but clearly a lot of effort went into the paint and pad-printing on the model. The lettering, even some of the smaller details such as the “lift here” at the jack pads is clearly readable – the resolution of some of the graphics, such as the builder’s plate, is probably beyond the capability of my eyes to read! Likewise, separately-coloured handrails, handrail stanchions, grab irons, cab interior, and exhaust stack all contribute to the superb appearance of the model.
- The Motor – I’m told this model uses a new motor for Bowser products, which likely explains the size of the flywheels on the motor shaft. I didn’t measure them, but they appear to be a good bit larger than the old Athearn Blue Box flywheels, which seem to help the model operate quite smoothly. The motor is surrounded by a great deal of weight, which should give the engine plenty of traction.
- The Wheels – one thing I thought was a nice touch was that blackened-metal wheels were installed on the model. No shiny silver wheels that need painting on this engine! To me, this is one of the details that set this model apart from other high-end manufacturers, or even brass engines. Additionally, Bowser included extra bearing caps in the packaging - CP has a habit of exchanging the enclosed Hyatt-style bearing covers for exposed-cap bearings, similar to freight car bearings where one can observe the rotation of the end cap. Bowser included a set of spare bearing caps so that the unit can be detailed per prototype, if it has received replacement bearing caps.

Two minor things (really minor) caught my attention as minor areas for potential improvement. The first, a detail difference, is that the CP SD40-2’s feature an angled drip rail above the cab side windows. The model appears to have a straight drip rail, which is at most a minor correction. The second is not so much a detail issues as an operational one – the front pilot interferes with the coupler trip pin on the car coupled to it (assuming trip pins have not been removed from one’s rolling stock). This is not an issue unique to this model, but almost any engine that has a snowplow; I first noticed this phenomenon on an Athearn Genesis GP38-2W. My solution on that engine, likely on this one as well, will be to install a long-shank coupler on the front of the engine to avoid contact between the trip pin and the round style rock plow on the front pilot.
Again, this is not meant to be a complete review or any sort of advertisement for Bowser, but it is hard to overlook the massive amount of detail that went into creating one of the most detailed (and one of my most favourite) HO plastic engines anyone has ever produced.
‘Til next time,
Cheers,
Peter.
