I think in model railways you need to make a choice on what you spend your money on. Somethings are worth it and some really aren’t.
Today I knocked up a short track on which to run in locos using a rolling road. I have the DCC concepts one and it really is worth the money. Easy to use, well made, worth every penny.
I used it today to run in the replacement chassis I got for the 43xx Mogul.
For lubricating it and attaching it to the body, I put it in a cradle. You can buy proper cradles for locos but I really don’t see the point. I use a sponge that cost 50p from a local supermarket with a slot cut into it with a scalpel. Even the cheap one from Peco costs in the region of eight quid.
It must be pretty a pretty awesome type of sponge to be 16 times the price of mine.
