Red double deckers

Amongst the releases promoted by Piko this year, some older models cascaded from Classic to Hobby range caught my eye. These were the refurbished ex-DR double deck coaches in traffic red. This shuffling was accompanied of a RRP reduction from Eur93.49 to 39.99 in the case of driving car, and from 69.99 to 29.99 for the all 2nd. Previously these coaches has only been available in the Hobby range as (innacurate) Metronom examples. With such a saving, some economies were surely inevitable. Nevertheless, I placed an order for a couple and waited...

 

Last week, they finally found their way to my post box. Although they weren't the most common type on Rügen (this falls to the unavailable-as-a-model DABbuzfa 760) they were certainly present around 2000, so they're the best thing available to me for my Regional Expresses. Like an excited child at Christmas, I eagerly pulled them out of their packaging for a good look. Naturally, the driving car (DABbuzfa778.0) draws my attention most.

Shortcuts or otherwise, it certainly looks the part. Without going into any great detail, the only thing that gives me any cause for concern in the basic model is that perhaps the cab isn't raked back far enough. Have a look at the prototype to see whether you agree.

 

Really my concern with these models isn't any fundamental accuracy issues, it's what detailing they might need to be brought up to a similar standard to my Roco coaches. With the financial saving compared to the classic models, I'm prepared to put a bit of effort in. So rather than being a review, this post mainly concerns my search for the modelling I will want to do.

 

The biggest job is the window frames. They're aluminium or something on the prototype, and in the catalogue images they appeared painted. However, those catalogue images were probably actually the classic models. The unpainted clear plastic on the model just doesn't look right. I have tried painting window frames previously, but it's tedious and needs a good steady hand, which I don't always have. I think my best option might be to try drawing up an etch to make overlays from stainless steel. They'll be a nice straightforward thing to learn etch design with too.

 

Another obvious area is the bogies. Compared to the classic model, Piko have reduced the number of parts drastically. It's essentially just the basic frame now, no brake rigging or other details. Here's the leading bogie, drivers side of a Piko "Classic" DBmq776.

As you can see, it has brake blocks nicely in line with the wheels and an indusi (German AWS equivalent, a bit more like ATP) receiver. Now, the equivalent view on the "Hobby" DABbuzfa778.0.

It shouldn't be too hard to make up the missing details. They are different on the DABbuzfa778.0 to the DBmq776 though, and there is the addition of sanding gear.

 

There's also quite a lot of printed detail.

I'm not sure what I'll do about this, I always find it hard to blend added details into the factory finish. I'll just see how much it bugs me over time for now!

 

Finally, the model lacks factory fitted lighting. However, it is available as an accessory part, but at 30 Euros I will probably just make my own. It's not a job I find tricky!

 

As a closing note, a front end comparison between the "Classic" DBmq776 and Hobby DABbuzfa778.0.

Nice review. But ouch the cab on the DBmq776 looks like a total after thought! Asthetic design wasn't top of the brief with that one. A former DR design I guess?

 

Never ceases to amaze me how many different designs of double deck stock there are in Germany. I'm most familiar with the

Munich, Landshut, Muhldorf and Passau areas on Germany (I have family there) and the driving cars in use there are different again.

I'm not quite sure what you are referring to here, Rich - the 778 series and 760 series driving trailers (the latter of which you linked to here) are, in fact, that different in their external appearance, with the 778s having been given a cab front based on that of the Bombardier double deckers.

Okay - I thought as much, but wanted to ask just in case you were meaning to make a point which I missed :) .

Yes, that's the original DR cab design, and I agree that it looks, well, ugly :lol: . Interestingly, the 760 series driving trailers have cabs which are mostly identical to those on the class 143 electrics, including the speed control function, thus providing additional driver comfort.

I guess you were referring to the 761 and 762 series driving trailers as well? Far as I remember these were first introduced in Bavaria. They can also work with class 218 diesels, which is why I suspected you were referring to them when you mentioned Mühldorf.

I didn't really intend this as a review of the model, more a preview of the work I'll do on it!

 

I know what you mean about the number of different dosto designs, I keep thinking I should buy the book I've seen about them, but I have a feeling the story ain't over yet.

I see you replaced the link, Rich :) . I understand you were meaning to compare these refurbished Dostos to the Bombardier ones, such as this 766 series driving trailer? From what I can tell (having seen both types in parallel around Leipzig), the front actually is a bit less raked on the 778 series.

I agree with your feeling - have you seen this Bombardier press photo of the newest generation yet?

The front closely resembles that of the class 442 "Talent" EMUs, including crash protection elements according to the newest UIC specifications.

Hi Dominik, in the rake of the cab I'm purely comparing model to prototype.

 

And I think you've done my trick and given the same link twice where you meant to give two different ones!

Oh, I see. That I haven't been able to compare as of yet.

You mean the bit with the 761 and 762 series? There are some differences between these two types, although they pretty much look alike. Looking at the type designation, the 761 series one has the following properties:

 

D = double deck

B = 2nd class

b = provisions for handicapped passengers

z = ETS power supply

f = driving trailer with TDM controls and/or 36-pole command cable

 

Meanwhile, the 762 series has these:

 

D = double deck

AB = 1st and 2nd class

p = open coach with central aisle and air conditioning

b = provisions for handicapped passengers

z = ETS power supply

f = driving trailer with TDM controls and/or 36-pole command cable

 

 

Also note the different placement of the ventilation grilles towards both the cab and vestibule end on the upper level, as well as the different window layout on the upper level.

 

Perhaps I should have pointed this out in my previous posting...my apologies :unsure: . I'm still quite groggy from hauling furniture till late last night and the subsequent drive back from Koblenz.

Hi Dominik, I don't mean the "early DB" 761s and 762s, I mean in the following post you link to the same pic of a 766 twice rather than showing the latest Bombardier product!

 

Why do I feel an order to Ian Allan for this book coming on? Mind you, at a 2004 publication date, there's going to be a lot not covered!

*facepalm* You're right :mellow: . Well, let's try this again:

Whoah! Autocouplings? Are DB planning to take NS's lead and fit some locos with auto couplings for push-pull operations?

I haven't heard of the DB going quite that far yet. However, far as I did read thus far, the idea is to also offer powered driving trailers (!) so as to allow the formation of what would essentially be multiple units with a variable number of intermediate trailers - for which I think auto couplers on the cab ends would make quite a bit of sense. This, of course, would constitute a kind of revival of the class 445 "Meridian" EMU which never went beyond the prototype stage. Of course, I guess those powered driving trailers could also be used as booster units of sorts for loco-hauled formations, provided they would be fitted with the same MU control package.

For the sake of completeness - this is what the 445 looked like: Click. I believe one of the reasons why it was never ordered was that the doors - especially on the driving trailers - were considered too narrow, thus unacceptably slowing down the passenger flow. However, I believe this issue mostly applied to suburban operations, for which the 445 was to be used as well. On regional workings, I personally would assume this to not have been much of a problem.

 

Also, the traction equipment was quite voluminous, taking up lots of valuable space above the bogies, which I think could and would be done differently nowadays. Being a prototype, the 445 used many off-the-shelf components also fitted to locomotives, where of course passenger space is not a requirement.

This is highly informative, given that I've just taken delivery of a Piko ex-DR Dosto to run behind 18.201 (which, incidentally, seems to have only been pictured hauling DoStos on a very limited number of occasions), and the various coach classifications are fascinating.

 

The DR-designed "DBmq" cab-end owed nothing to aesthetics and everything to expediency. Viewed head-on it reminds me of a cartoon character.
