The Johnster

Hello.

I've been advised to direct at query to you so have copied and pasted it below.

I have used this as an alternative to traction tyres on an Airfix Class 61XX tank engine and found it to be fantastic. (Apparently replacement tyres for these models aren't manufactured by anyone.) My question is has anyone ever tried it on wheels which do not have a groove for traction tyres? I have a Chinese made Hornby Castle Class, (I don't know the R number, but it's named Isambard Kingdom Brunel), and while it is a great looking loco, its haulage capabilities are limited to say the least. There is a slight gradient on may layout, not intentional, but due to my poor woodworking skills when building the base boards which has resulted in a rise of 2mm over a distance of 9' which works out as a gradient of approximately 1 in 1350. The Castle spins its wheels like mad when travelling along this section hauling six freewheeling BR Mk 1 coaches sometimes to the point of refusing to move. Other locos including a 1960's Tri-ang Hornby Albert Hall have no problem with the same load and I was wondering if a thin coating of bullfrog snot on the Castle might help. All opinions welcome.

I would add that I am aware of the electrical pick issues and only intend to treat one wheel (as per the Airfix prairie only having one tyre fitted).

Thanks in advance.
