'Lindow' has arrived

A new toy arrived yesterday!
It's a Ride-on-Railways 'Hercules' battery-electric locomotive named 'Lindow'. I might add a bit of detail - brake hoses on the front buffer beam, cab-roof horns, exhaust stack. But first, we'll see how she runs on the track.
It's heavy and powerful (4 big motors, 2 car batteries) so should pull a fair load at the track. I've run her on rollers and all seems well, so I look forward to taking her to Urmston.

I have been planning to have a battery electric locomotive to supplement my 5" gauge live steam fleet ('The Wildfowler' and 'Warspite') for about a year. I first considered 'scale' models of main line diesel locomotives, in particular a lovely model of a BR Western Region diesel hydraulic 'Western' class locomotive. The 'Western' has always been a favorite of mine, and by chance a superbly constructed 5" gauge model of 'Western Champion' was for sale locally.

'Western Champion', which I considered buying at one point
The problem I discovered with scale models of main line diesel locomotives is their size; 'Western Champion' is over six feet long, far too long to fit in a car for transport to the track, and very difficult to store on a mobile trolley at home (these locomotives have to be wheeled around on a trolley to get them to and from the car as they are far too heavy for even two people to lift). It's true that my Jubilee main line steam locomotive is also around that length, but the tender detaches from the locomotive so they can be stored and transported side by side.
So with scale main line locomotives ruled out, I looked for an alternative. As well as being small enough to manage it would need to have good traction with as many 'driven' wheels as possible, be powerful enough to pull a fair passenger load, and heavy enough to put down the power without slipping.
I looked at several alternatives and decided on a non-scale generic design, the 'Hercules' from Ride-on-Railways in Romford, Essex. It didn't look as elegant as the 'Western' but it did tick all the other boxes. At three feet long, less than half the length of the 'Western', transport and home storage would be no problem. It has two 4-wheel bogies, with each of its four axles powered by a 150watt motor. It also has fly-cranks so the wheels on each bogie are inter-connected, much reducing the chance of wheel-slip.

I enquired if any 'Hercules' locos lived locally so I could see one; none came to light (though I later learned of at least two), but a member of the Mid Cheshire club offered to show me his 'Trojan', based on one of the two motor bogies of the 'Hercules'.

The little 'Trojan' impressed me with its eager performance and good build quality, so I ordered a 'Hercules' from Ride-on-Railways. Lead time to delivery would be a few months, which gave me time to choose a colour scheme. Ride-on-Railways offer their locomotives in a range of standard colours, the bodies being painted all-over in one colour, but customers can choose custom colours if they please, at extra cost if more than one colour is specified to cover the cost of time consuming masking-off during painting.

A 'Hercules' in one of the standard colours, and without the cranks and coupling rods on the bogies (an option). I specified the bonnet hand rails to be positioned on the sloping part of the bonnet rather than the standard position shown here, in order to allow space for the 'Lindow' name plates on the bonnet sides.

The 'Hercules' has a slight look of the BR class 14 'Teddy Bear' locomotive, with its centre cab and two bonnets, one longer than the other, and I rather like the dark green and lime green scheme some of those locomotives carried.

Using MS 'Paint' on the computer I set about constructing 'artists's impressions' of 'Hercules' locos in various schemes. After many abortive trials, I came full circle to my first thoughts, and  settled on a scheme inspired by the Class 14.

Final 'artist's impression' of the colour scheme for my 'Hercules'

Ride-on-Railways use Halfords car paints and ask customers who want a 'custom' paint scheme rather than a standard offering to choose their colours from that range. After some trial and error, I found the two from the Halfords range that were closest to the colours I wanted; Vauxhall Reed Green for the cab, Rover Brooklands Green for the bonnets.

Hardening-off the paint under the heat lamp. This picture sent by Ride-on-Railways gave me my first opportunity to see my chosen colours applied to the body. I was not disappointed; it looked good.

Nearly ready; just needs name plates and builder's plates fitting

Opening rear doors give access to the battery master switch, on / off switch, speed reduction switch (limits maximum speed for use of inexperienced drivers), and battery condition and fault indicator panel. The hand held controller plugs into the socket lower right so the body can be lifted off the chassis without having to disconnect it.

The final job was to chose a name. Several were considered based on geographical features of the area, such as 'Bosley Cloud', 'River Dane', 'Redesmere', 'Shutlingsloe' etc. I also considered 'Lindow Lady' or 'Lindow Moss', but in the end decided simply 'LINDOW' would be best. You can't get more local to where we live than Lindow. Our children attended nearby Lindow Primary School and the loco, as well as celebrating our local area, is in part a tribute to the late Peter Helliwell, inspirational head of that school. The name also gives a nod to the narrow gauge railway system that ran on Lindow Moss as part of the peat digging operation, though nothing larger than a tiny 4-wheel rail tractor ever ran on that railway.
The 'Hercules' has about the same power as the 'Western' I considered, having four 150 watt motors driven through an electronic control system from two car batteries. It also has regenerative braking, so as the controller power setting is reduced, the motors are used as generators to slow the train and put power back into the batteries while so doing.

Behind that is the control panel with the battery isolator switch on the left, the on / off switch next to that, and the half-speed limiter selector switch to the left of the battery condition / fault indicator panel. The hand controller is resting on the chassis base plate. 

The 'Hercules' is a similar weight to the 'Western' but is far easier to transport. As well as being about half as long, it dis-assembles very easily into smaller units for transport. The body simply lifts off the chassis, the batteries have 'quick release' connectors and carrying handles so are easily removed and replaced for transport, and if required, undoing one nut on each bogie pivot and one electrical plug per bogie allows the bogies to be removed.

Weight breakdown of a 'Hercules'. The loco is designed for easy disassembly so it can be broken down into easily carried units for travelling between home and the running track.




All that's left to do now is to run 'Lindow' at the club track, pulling passenger trains after trying some loaded test trains to see what sort of passenger loads the loco is happy with. Christmas and New Year will delay that, so it'll probably be early January before she gets a chance to show her paces.
