Ive created a linepack for Bowdenham V5 which has line -

1. Town Service    Spawn Point Apsley Bus Station

177.  Herford Station to Wotton Asda

222. Knockhill Bussiness Park to Apsley Station

541. Wotton Asda to Hockley Ried Parade

You can find the map at https://fellowsfilm.com/threads/bowdenham-v5.16507/ and ther author dazz1980 done a great job on it.  

To install the linepack just drop the the bowdenham chrono into the bowdenham map file or drop the bowdenham map from file into the omsi 2 directory.

Hope you enjoy Michael
