I recently used Railzip for the first time.
I dutifully followed the instructions on the bottle ie applied Railzip with a cloth, left it for 12 hours and then rubbed the rails with a cloth.
I tested all my 0-6-0 tanks engines and a Class 08 shunter and their performance has improved beyond measure.
However, my Class 37, Black 5 and 2-6-0 now all suffer from poor traction. Anything more than a carriage really makes them struggle.
I've tried to clean the wheels of all three and the performance of the Class 37 improved but it's still nowhere near it's previous performance.
Any idea's on what I can do for my tender engines?
