Someone asked me whether there was any information about what happened to these locos in any of the main texts about the metre-gauge lines in East Africa. The only specific reference appears to relate to the locos going to the 'Yunnan Railway'.
It might be that others can shed more light on this, but I thought that it was worth following up. The post below is the result of this.

Research suggests that there are two possible locations for these locos operations after leaving East Africa. The first, initially seeming the most likely, is the Burma-Yunnan Railway which was a British project. The second was a French project. We spend a little time focussing on each project before some final observations are made at the end of this post
