47 004 – Onto the big Brush 4’s here and this particular model has been included on here as it is a bit of a pet project of my own. This is a Bachmann 47 model, but has a Penbits Etched Brass spring Chassis underneath it, with EM Wheel sets. Still a work in progress to dabble at when I have the time, the chassis and running height still need some tweaking, but if you’re after some extremely realistic running loco’s then the Penbits chassis are an absolute delight to behold. Complete with primary and Secondary springing, they enable the model to ride along in exactly the same manner as the real thing. Penbits website can be found at: http://www.penbits.co.uk
