The new 2017 Hornby 14xx is now in the shops.
I have had an old Airfix/GMR 14xx since 1983 and it has never run well and recently completely conked out (shredded gears I think). However, it was the first locomotive I ever purchased with my own money and therefore one of my favourite engines.
I have the new DJM/Hattons 48xx and 58xx but did not want to throw away my treasured 14xx.
So I decided to buy the new Hornby effort to replace the chassis on my old Airfix body. And doing this would cost 1/3 the price of the new superior DJM model.
The new chassis fits exactly under the old body. The only issue is the chimney screw is of a different diameter/thread so I used the new chimney and screw with the old body and new chassis.
My old Airfix body is even better than the new R3589 variant - which is GWR livery and has a superfluous blank smokebox numberplate.
It is a little noisy for modern standards; it still has the annoying traction tyres (but a far better profile than on my old model) and is a little tight through my Peco Streamline Code 100 points so I will check the back-back when I have more time.
But overall I am very pleased. My favourite engine is running far better than it ever has in the last 35 years, for 15 mins work.
And now you cannot see the motor through the cab windows.
