Streaks and Highlights – Weighing up Bachmann A4s


Silver Sidelines

I noticed a thread this last week asking if anyone had comments on the ‘new’ Bachmann A4s – here are mine!

I have fond memories of A4s speeding past Darlington Station hauling the Elizabethan. Hence it did not take much persuasion for me to buy one of Bachmann’s latest A4s with a new DCC ready chassis. Initial impressions are of a well engineered model that I think looks the part and compares very favourably with the latest Bachmann A1s and A2s.

Bachmann A4 DCC Ready Chassis

 

Out of the box with a weight of around 335gm the engine is I feel a bit light. The motor has lots of power but when hauling seven coaches on my steep gradients there was too much wheel spin. The reason for the low weight is obvious – there is big gap for a decoder. Yes I removed the front bogie and Cartazzi axle springs but there was still a lot of wheel spin.

With so much space it is relatively straightforward to add extra ballast in the shape of lead shot and lead sheet.

With the ballast shown above the engine now tips the scales at around 365gm – a decent improvement.

Bachmann A4 split axle chassis

 

How does the new model compare with the old model with split axle chassis? Straight out of the box the early A4s weighed close on 380gm. Removing the front bogie and rear truck springs gave the model I thought a half decent haulage capacity.

However on my layout there was still far too much wheel spin so I needed to add some extra weight. As shown above the split axle chassis model plus ballast tipped the scales at 405gm – pretty useful.

Bachmann A4 Bittern with split axle chassis

 

I like my Bachmann A4s. Suitably ballasted they all perform very well. My new model of Willie Whitelaw is perhaps smoother and quieter than the early split axle models. The new motor appears to have more torque. Certainly the control knob on my Gaugemaster controller has to be turned further round compared to operating the split chassis models.

 

For those of you who can bear to watch trains traversing unfinished layouts there are a couple of videos on YouTube:

YW. You know I share your opinion about Hornby & Bachmann. However, in this peculiar case, the tooling of the Bachmann model is much older than the Hornby one, so the comparison may be controversial. Other members of the forum may find such a comparison of much interest.

Thanks for the articles on the A4 and the A1 Ray. I shall probably get round to adding a Bachmann A1 at some stage so your information regarding the improvements is most welcome. 

 

Re comparing the Bachmann LNER locos against the Hornby, I only have a late crest V2 60825 from Bachmann and I have a Railroad A4 Falcon and a loco-drive Gresley A1 Gladiateur in apple green.  

 

Comparing those three the V2 is a relatively old model.   I do have a soft spot for it.  The detailing is a bit chunky in places, but you at least you know it is sturdy to handle. Despite it's split-chassis age and old body, it's a very reliable and smooth runner. I've not needed to do any major work on the loco, save for a quick shortening of the tender gap and then re-soldering the cartazzi truck pick up wire connection once.  She pulls all the loads I normally use (say up to 6, 7 or 8 coaches) fine. The more recent locos from 31-560+ are well worth their bargain prices. I am very tempted to add the current BR Black release!

 

The A1 Gladiateur is the current/recent loco-drive engine.  I've had it for a good few years and it has been faultless - far better than some of the recent Hornby locos I've had!  The motion work is very fine so it needs careful handling whereas the Bachmann locos are a lot more sturdy in that sense.  Some people state the Hornby rods are too thin.  In relation to performance the A1 has been excellent.  It has been faultless and will pull anything I put behind it.  Bear in mind these have the fixed cartazzi truck; thus if you have train-set radius curves the truck overhand is very noticeable.

 

The A4 Falcon is in garter blue.  It shares the same chassis set up as the A1: hence excellent running.  However, the tender is the old tender-drive with the old connection.  I've shortened the tender gap slightly.  Given all the old weight in the tender the A4  is not as strong or as fast as the A1, but still pulls 6-7 coaches happily.  For the price if you can get a bargain on these they are a good buy if you're willing to put up with the limited body detailing (there is no cab glazing).

 

Cheers,

Hello John

Thanks for your observations.

I am not a great fan of Hornby locomotives and know next to nothing about their Railroad Range other than being told that the Railroad A4 is very good.  I was seduced into buying a Super Detail A3 which is a very fine looking engine but like you I am thinking that it not as solid as the Bachmann range. I do like the Hornby Britannia.   At one point I had all Mainline and Airfix models but most of these have been moved along and replaced with Bachmann types.  My first Bachmann model was the V2 and I couldn't believe how smooth and quiet it was compared to the Mainline range.  The V2 comes in for a lot of criticism here on RMweb because seemingly dimensions are wrong.  May be it is too 'chunky' but it is still a very useful model.  If we are content to run our 4mm scale models on 16.5mm gauge track we have to accept some other compromises.   I agree with your thoughts regarding the delicate nature of the Hornby valve gear.  Perhaps there is too big a contrast with Hornby's chunky wheels.  Bachmann wheels besides being cast metal seem to have slightly narrower tread and look more the part?  I think the second hand value of the respective models is a good indicator of quality.  Looking in on eBay I would say that Bachmann models generally command higher prices.
