Bachmann Double Fairlie length

[Graeme Dunbar]

I would like to know the length of this loco over the couplings please.

I don't have one and am not planning on getting one at the moment but I'd like to make allowances for its length in the ScOONs modules I'm building.

(What I'm building does not have space for a proper headshunt or run-around loop but I'm hoping I can squeeze in just enough space to do so at a push when running a minimal modular layout configuration. I reckon I've enough space to run around small locos and would like to see if a Double Fairlie will fit too, even it it means ramming the buffers to do so.)

Thanks.

Mine is 122mm over the couplings.

Hope this helps.

Many thanks!

The measurement you need for a head shunt is from one coupling to the wheel that is furthest away. The total length will include both coupling overhangs, but you only need one for the length of the head-shunt. 

For running round you will also need to know how far the cab section is off the center line of the track on a curve as it goes around the end of the rolling stock. (You will also need to know how wide your rolling stock is.)

Yes, that is pretty much the line I am planning to take. So long as the wheels clear the point blades when whatever is at the other end touches the buffer stops to prevent the loco falling off the end I'll be happy. There will be rather more clearance when shunting smaller locos which should look less artificial - at least as much as is possible on a tiny module.
