Maxitrak Planet 2 Locomotive Arrives!

A momentous day with the long-awaited delivery of the Planet locomotive.

 

It was very well packed in a wooden crate with foam packing on all sides.  The battery drill got a workout unscrewing numerous screws holding the crate together.

Finally, after freeing the loco from the crate, one end of the crate was used as a makeshift ramp to roll it down onto the track in the garage.

Mini Train Systems had separately shipped the plug-in speed controller, so it was a simple matter of plugging that into the rear of the cab, closing the main circuit breaker and away we go for the first test run.

Across the Driveway and Beyond

The remaining track to the driveway, on a downgrade, was relatively plain sailing, compared to the cutting.

An advantage of working on the track in winter was that it was clear where water tended to accumulate necessitating drainage measures.  At both side of the driveway, 60 mm slotted drainage pipe was laid under the track and the trench filled with ballast and/or larger rocks to allow water to percolate through.

The next section of track from the driveway along the side of the lily pond was always going to be tricky, as the ground level dropped by 400 mm over a short distance.  Initially, I started using the soil removed from the cutting to build up an embankment to try to maintain the 1 in 50 maximum, but it soon became clear it was going to require a lot of dirt and, as the ground level continued to fall, the embankment might never reach natural ground level.

Plan B was to relay several track sections based on a steeper 1 in 33 gradient, and also dig a shallow cutting immediately past the driveway so the downgrade would commence earlier, to limit the length of the embankment.  

In the photo below, the track on the left is on the original embankment, and I have removed the track and ballast from the centre section in preparation for lowering the embankment.  The track on the right is at the new, lower level.

After relaying this section, the resulting track height fits in much better with the general lay of the land.  The piles of dirt to the left of the track as what I removed from the embankment plus more dirt removed from the cutting earlier.  The excess dirt will probably be used somewhere else along the line as there are some low lying areas in the back garden.

Interim Driving Truck

After receiving word from Mini Train Systems that my loco was nearly ready to be shipped but the wagons I had ordered from the were still some months away, I decided I needed to quickly build some sort of wagon to function as a "driving truck", ideally with a manually operated brake.

DNC System Technologies seemed the best source to obtain a pair of bogies, so I ordered a pair of their archbar bogies with the mechanical brake option.  After placing the order, DNC responded quickly to my email and provided a drawing showing the overall dimensions including the diameter and height above rail for the bogie pivot.

Armed with this information I designed a rudimentary wagon underframe which I could build with the tools and skill available.  I built the underframe in Perth and the 1.2 m length allowed for easy transport in the car to Denmark.  The main metal parts are the bolsters, which I cut from a surplus 50 mm square steel fence post, and the end sills which I made from 50 mm galvanised steel angle, also surplus from another project.  The idea was that the metal parts would fulfil the main load-bearing requirements, with pine for the remainder all held together with numerous screws and some angle brackets.

By chance, while searching online for a photo of the braking arrangements on the DNC bogies, I discovered a pair for sale on Gumtree in Mandurah, WA.  They were nearly identical to what I had ordered, except only one bogie had brakes.  As the order from DNC was going to take a while, I decided to buy the secondhand bogies as "insurance" so I would have something to use as a driving truck when my loco arrived.

It was a few weeks and another trip to Denmark before the underframe and bogies were united to form a functioning wagon.  I used a brake lever purchased on eBay and intended for use with a caravan or trailer to activate the mechanical brake just on one bogie at this stage.  A plastic step stool provided rudimentary seating for one person.

Somewhat following prototype practice, a long lever increased the braking force and also provided a point of attachment for future brakes on the second bogie

Another milestone reached with the first wagon on the railway able to carry a human passenger (but still no loco)!
