LSWR T9

[richak]

My Hornby T9 loco is a very smooth runner and good for slow running and shunting but will not pull two carraiges up a gradient of approximately 1:40 and suffers wheelspin. Is it possible to apply weights to help the traction or is this harmful to the motor?

I don't think it would be a problem. You are not going to be adding "pounds" - may be some weight in the boiler if there is room - may be "fishing" leadshot? It may be a case of trial and error. I have a T9 but it's never been out of its box - does it have traction tyres?

Adding adhesive weight.

I have a large fleet of over 100 tender locos, and most have had to have added weight to improve their haulage abilities on my 25ft long 1 in 100 gradients, as I expect my models to haul real life loads in line with their real life capabilities.

 

When adding weight I use Fishing tackle lead shot. The small 0.10g/0.25g/0.40g sizes I find most helpful as you can squeeze dozens of these into every nook and cranney. I use UHU as this doesn't damage the plastic and if necessary you can prize the lead out again if necessary !

 

A tip when adding weight. Try and get the added weight over the driving wheels, or you may unbalance the loco and the extra weight will become counter-productive.

 

If there is little space inside, and you have to add weight infront of, or behind the drivers, this will work if you put an equal amount in front as behind. So for example if you add 5g inside the smokebox, you need to get 5g somewhere under the cab area.

 

With the T9, check that the traction tyres have not come loose. Hornby add a type of "tacky" glue to help the traction tyres grip the wheels, and if this has failed the tyres will slip and not do their job properly.

 

NEVER PUSH a traction tyre fitted loco EVEN AN INCH along the track, as this will most likely strip the traction tyres free and stretch them so they become useless !!!

Before adding weight, check that the coil spring holding the bogie on the track is not exerting too much force such that it is tending to take some weight off the front driving wheels reducing the effect of their traction tyres.
