As everyone is aware at this moment we in the Uk are in the middle of a bit of a freeze.! So this morning went to run on the railway to discover all my points frozen solid. So My Mothers solution was to boil kettle and pour boiling water over the points. This cured problem for 10 minutes or so. Then points froze even harder so this caused problems running. Especially as I was running my new aqusition ( A Piko 80 Tank) so apart from building minature point heaters any ideas on how to keep points defrosted !!
