Locomotive weight vs traction tyres?

Dorset   Mike,   Its   a   very  impressive   video   for   such   a   small   tank   engine   to  haul  as   many    coaches,  but   being  realistic  in  real  life   I   doubt  if  they   ever   hauled   more  than  4.

Certainly impressive haulage power.  'M7s' were powerful locomotives and this was put to good use on the Waterloo ecs trains.

Many thanks for the video.

Best wishes.

as John says they were employed on empty stock workings between Waterloo and Clapham carriage sidings, typical loading would be around 12 bogies, and in that area lines were very busy with suburban electrics as well as main line services so they couldn't dawdle.

The worst thing is a light loco without traction tyres. Both Dapol and Farish have done this. I have been told that the Farish Castle doesn't have traction tyres so there are more pick ups for the sound version. If the power is lost even for a split second by the sound version it has to start  from zero with its inertia slow start. If this is correct then the model has been compromised for most users for the benefit of the high priced sound version.

I'm very happy with the pulling power of fairly light locos with traction tyres. I'm not at all happy that Dapol can't be bothered to supply spare traction tyres. I'm pleased that the Farish 2-8-0 Austerity tyres fit the Dapol 28xx.

ALL of my Dapol tender locos have a goody bag of traction tyres in the box.  Having said that when a tyre starts to go out of round I treat it as time to send the loco off to DCC Supplies for a service.  But then again my locos lead a hard life.
