The investment into development was smaller because of lack of money. But they haven't stopped and they showed a new high floor EMU.

I think financial difficulties won't change much because now they're much bigger than just a few years ago. Only this year Newag expects to triple its total revenue (from 300 million zl in 2011 to ~800m zl in 2012). Pesa and Newag are pretty difficult to take over because they are private copmpanies owned by just a few guys with big ambitions. Newag is owned by one multimillionaire - Zbigniew Jakubas and they've already struggled from financial difficulties once and Jakubas said that selling Newag was never an option.

About complications. First - they haven't got so seriuous complications like Siemens with Combino. Newag had some with their first DMUs, it took them about 2 months to fix. To avoid such problems they produce prototypes to test them and results are pretty good - Newag 19WE (which has a prototype) is the most reliable Polish EMU, it's really close to Stadler Flirt. Now Newag is testing the prototype of their first tram.

PS. Two things about Pesa:

1. They have one more order abroad for 30 Links for Czech Railways (CD).
   
2. Link from Innotrans was produced for Zachodniopomorskie voivodship in Poland, they just painted it in Oberpfalzbahn livery.
