About Me

My photo
When i left school back then i was lucky enough to enroll on an engineering apprenticeship. I think this lead me in good stead. I was always one of those children that pulled things apart but actually put them back together again. My first engine given to me at the age of Seven, a Triang Princess Elizabeth. The rest as they say is History. Later in life i got back in to Model Railways and started building Pine Road. This could lead anywhere so i hope you enjoy my Blog.

Hornby and their Terrier part Two.

Ok, this is all fascinating stuff. Hornby, it's Terrier and it's running qualities.
This is an update from my last post, so if you have not seen that yet, It may be a good idea for you to have a look there first and all will make sense.
After discussing the running qualities of Hornby's new Terrier with a friend of mine, he suggested, what would it run like on an old feedback controller?
Plugging in my old Gaugemaster feedback controller, (thats the black one) the terrier is a whole new beast.
I am now befuddled, confused and basically annoyed.
I think there is a good article here for one of the top magazines to take on. Are we now at the point of swapping controllers for different locos? Is this progress? Coreless motors etc.
Over the years we have all read stories about the old H&M controllers on half wave, modern motors don't like them. Then told not to use feedback controllers with coreless motors or can motors.
Its all getting very confusing.
It's another good argument for DCC, like it or hate it, the system seems to cope with anything and, the old myth of "if it won't run on DC it won't run on DCC" has been blown out the water with most decoders these days having BEMF (Back Electro-motive Force) which can also be adjusted through changing some CVs and adding stay-alives.

I had a thought
Instead of your straight forward sort of blanking plate for general DC running, could this be made to contain some sort of BEMF circuitry?
