Originally wanted to ask id any "x" got these bogies. But seems not.
So for the well informed, what other locos around the world got similar looking bogies ??
The early and later cast Flexicoil bogies are interchangeable.
There is nothing stopping the early pattern being used on an X class.
The Fabricated bogies were built when there wasn't enough foreign exchange to buy cast bogies from the USA.
They lasted around 1 million miles but developed cracks and were replaced. They were used on the B class.
Later bogies were cast locally, initially in two pieces welded together over the centre axlebox.
The bogies on the ex Danish MZ3 locomotives are fabricated and look generally similar to the early VR bogies.
The bogies on early EMD SD7 and SD9 locomotives look like the early fabricated bogies and the early cast bogies.
These are longer, about 12 inches longer overall.
The Lima HO S and B models used bogies built to the American dimensions.
