Re: On3/On30 diesel project...

I think you also need to consider what the current generation of meter-gauge GE locomotives look like. I would expect that if the White Pass buys new locomotives it would be like the new order of meter-gauge C23EPM for a Chilean line -- this are like some C23EMP locomotives sold to an operator in Bolivia in recent years.
GE expands into Chile

Here are links to some YouTube videos of one of the Bolivia GE locomotives:




GE C23EMP DE-2305



General Electric GE C23 Bolivia



Duplex GE C23CM/U20C Bolivia

There are a number of interesting videos of GE meter-gauge locomotives on this YouTube channel.
