The old trainset will no longer be updated. I would introduce the successor of mentioned polish train set - Polish PKP Set 2.0.
This new trainset was developed from the scratch, using NML language. Because the set uses now wagons longer than original, all the sprites were repainted from the scratch too.
The Polish PKP Set 2.0 supports some interesting features:
- The longest wagon is 50% longer than normal OTTD wagon and supports 16 views instead of 8.
- The set checks the brake force. In older times you can not start the train if too many wagons have no brakes. You should use wagons with brakeman's cab,
- The passenger trains in arctic climate needs heating. You need use apropriate engine or special "heating wagon" to protect your passengers from freezing

The full list of available vehicles you can find in http://dev.openttdcoop.org/projects/pkpset/wiki . Intentionally, the Polish PKP Set 2.0 is compatible with FIRS and ECS. If it is not, please report a bug
