Better to come via Volvo, as it gonna route fully via Expway...
Asiad2x2 traverse through Expway, but divert smewhere to get over old mumbai-Pune Highway & so non-preferable...
If its via train, then there exist no suburb nearby and are as remote for Inst as Inst is remote for Pune City...Pimpri-Chinchwad can be nearby Suburb but still quite far-off & better to check local bus schedule online to plan better!!
