Firstly many thanks to those who have replied to my query regarding Bachmann B1's. Gluing did not work; does not take to the plastic inserts even when clamped up. So my loco is fit for just standing in a siding.......or is it? I re-assembled the chassis without the plastic driving wheel inserts - you have to look closely to see that they are missing but hey - runs a treat! I could go a step further and fit etched driving wheel balance weights and then you would have to look even closer! So next year my 61010 will go off to Grimy Times in Warrington and come back with a new identity - 61215 perhaps!
