So, moving on we come to the chassis in more less its first stage of completion. In the photos that follow you may be able to see the two 'ponial' trucks - essentially 'pony trucks' pretending to be radial trucks. This has been achieved by making sure the pony truck assembly takes advantage of the whole CSB beam that runs the length of the chassis (the wheelbase being longer than a 9f for those who are concerned with such things) as well as separately sprung lateral control. So we have four springs in total, hence the expression 'four-sprung durch technik'. The air reservoir tank is attached to the rear truck to make matters easier in the articulation of said truck

You may also note that the air reservoir tank has a groove filed out to accommodate the 10BA bolt securing it.

The High Level hornblocks have attached to them the spring carriers that also accommodate the CSB bearing surfaces, thus enabling the hornblocks to be removed at any time once the springy wire is removed, which makes inserting wheelsets a lot easier.

The more general side view might look a bit wonky, but is only due to the 10BA bolts securing the 'ponial' trucks not being washerd or tightened at present.

More anon, as I have been known to add...

Best,
Marcus
