Hornby Dublo running problem.

[jimwal]

I did a Triang 3MT on the 2-6-4T chassis with 'Montrose' cylinders and valve gear and Romford 21mm driving wheels. The chassis needed cutting shorter at the back and altering a bit at the front. I felt it was an improvement on the Triang chassis but as David says, now outclassed by the Bachmann Model.

 

I have an old H/D A4 chassis which many years ago became a test bed for magnet configurations prior acquiring a magnetizer. It had been cut about to take a Triang X04 magnet in front of the armature and another behind, with pole pieces of 16th" x 3/8th" strip bent to suit. Alas! it was unsuccessful, the motor ran fast with little power. This chassis has since been fitted with a 3/4" neo ringfield magnet. With the 3-pole armature it had bags of power but slow running was almost impossible. I obtained a Wrenn 5-pole armature and fitted it in place of the 3-pole and slow running ability was transformed!. It won't challenge 'Mallard' for the speed record so it awaits a loco more suitable.
