Tending to fence-sitting myself, I’ve always enjoyed excitingly bold projects risked by others. I once saw Bulleid’s CIE tufburner standing outside Inchicore works in the early 1960s and was instantly captivated.
There is some interesting material on the Douglas Self Crosti boiler site about Bulleid’s 1940s enthusiasm for turf burning that attracted the CIE Board to him at the time of the Milne (of the GW) 1947 visitation.
In particular how the poor old GS&WR Coey 1907 2-6-0 no. 635 got butchered by Bulleid into an extraordinary Crosti style turf burner in 1951 after what must have been a refreshing jaunt on the Irish taxpayers to post–war style setting Italy.

DS comments “As originally built, the steaming was awful, and a forced-draught fan was later added, powered by a Leyland bus engine carried on a wagon behind the tender”
We all know the actual boxy turf-burner CC! built in the 1950s (that I saw at Inchicore) by OVSB with John Click, his Leader class engineering assistant seconded from BR .
It was simpler and lighter than Leader with a central boiler (double Fairlie style) with a complex central cube shaped un water-jacketed firebox with thermal siphons. It adopted piston rather than sleeve valves but still used leaky oil baths enclosing the chain drive to the six wheel bogies. Turf and water storage was at either end.
It ran several times at 70mph, throwing turf sparks until fitted with spark arresters. Visibility and signal sighting was poor (smoke deflectors were only a partial remedy) It was clear to Click that redesign of both configuration and the double boiler was necessary before a new class of 50 could be introduced (dual fuelled oil/turf).
But CIE decided instead to dieselise at about the time of Bulleid’s retirement to Malta in 1959. Bulleid seemed to regard it as his private sports car; driving it himself, he treated visiting dignitaries to high speed joy rides.
As armchair CME I now propose to the Board of Imaginary Locomotives a 1959 redesign as a non condensing steam turbine/electric.
I fancy a 2 unit: tender/boiler & generating station (that might have multiple unit capabilities for powering 4 car trains of elderly Irish coaches on inter urban stopping services).
Could such a project be multi-fuelled ?
