Diesel hauled out of Praha hln-
Services to Ceske Budejovice via Breznice (table 200, the long way round) are 749 hauled. (rather conveniently linking the Budvar brewery, Herold at Breznice and the Beroun brewpub). Returns up the mainline are hauled by 363 electrics.
If you don't visit Budvar brewery try Budvarka at hotel maly pivovar in the main square or the beer hall opposite the bus station/shopping mall for good pints...
On weekdays some services to Cercany via Vrane nad Vltavou (table 210) are 714 hauled, on weekends some of these are 749 hauled plus there are 714s to Dobris. A slow but very pretty ride along the river gorge, sit on the right side exit Praha unless you like views of rock cuttings!
There are a handful of weekday 714 commuter services to Kladno.
On weekends there is also a 749 hauled turn to Tanvald and back.
PS for beer don't miss pivovarsky klub at Florenc and the 'Beer tram' at the end of route 11 on your travels, Zly Casy ( on route 11 too) is also well worth a look!
