What is a Trojan Loco?
Sharp corners and steep gradients on a garden railways create a great stain on engines. Un like many club tracks the garden railway will often involve hard acceleration and deceleration with little free running. This put a lot of strain on our two Bulldog loco's, so constant checking of the control board and motors coupled with regular breaks were necessary to avoid overheating - something that wasn't necessary when we ran on a club track.
The principle behind our loco is to over power it, to avoid strain on both control board and motors. If you try to pull too big a load all that will happen is the wheels will slip. So far even with too heavier load we have only managd to get the motors and control board luke warm.

Power is 24v from two
12v car batteries powering 4 motors (in parallel ie. 24v
each). We have to recommend leisure or traction
batteries, as car batteries are not designed for constant
current drain. That point raised our car batteries have
given over 2 years good service - your choice. Dimensions

| Right - The four
motors fitted provide more than enough power for those
occasionally overloaded trains. Removal of motors can be
done without having to split or remove the wheel sets. Should you ever wish to take the wheel sets out simply remove the eight bolts in the horn block guides and the set simply slides out. |

The loco now comes
with a welded on dashboard which allows the 4qd
controller to be bolted on. It also has a slot and holes
to accommodate the optional extras -
The board illustrated has had the control plug moved to allow for the "Saddle Tank" body |
