Today more then ever the Locomotive industry has numerous designs of new and rebuilt Locomotives aimed to smaller Rail operators. Typically these involve slightly improved mainline prime mover updates; or replacement of the original prime mover by genset power plants. Normally genset designs require multiple gensets to achieve the tractive effort and power.
In both cases there is often a fuel saving, oil savings and reduction of emissions. But for maximum emissions control, some sacrificing of power is often needed. And also Urea after treatment to reach the maximum Tier IV emission standard. Many operators are shy to add this extra consumable and maintenance item to their locomotives.
All of this tends to be rather expensive for railroad managers who are already facing slim pickings in the margin columns. But thankfully their have been some credits available, especially for Passenger services. But to date none for typical short/branch line operators of freight.
We would like to discuss these topics and examine any solutions coming forward. After all. We all profit from the improvements involved.
