London Historical Research Group

Welcome to LHRG

The convenors of LHRG apologise for the delay to Bulletin 224 (March 2023) which is printed and now being posted.  The electronic version of this Bulletin is available to OS members here.                                                                                                                                                                                       

We are sorry to advise subscribers that the June and September 2023 Bulletins have been delayed, arising from personal circumstances within the editorial team.  Bulletin 225 is in an advanced state of preparation, and we hope to be able to send this out in the near future.  LHRG will ensure that subscribers receive all issues that they have subscribed for.


The London Historical Research Group is devoted to research into the operation of buses, trolleybuses and trams in London, and is affiliated to the Omnibus Society. It was formed in 1963 with the purpose of co-ordinating the research projects of members and to provide a means of exchanging information on the history of road passenger transport services in the London Transport area*. It holds quarterly meetings in London and produces publications for sale, in addition to a quarterly Bulletin for its members. Meetings feature a talk on a relevant topic and range over a broad spectrum, as do the contents of the Bulletin.

Membership is via the Omnibus Society (click top right).  New members are always welcome.  Our contact details are at the foot of this page.  

Our major ongoing research project is Motor Omnibus Routes in London (MORiL), a detailed day-by-day chronology of London bus route introductions and changes, from the first introduction of motor buses in 1899 up to 1934. This history has been published in A4 format in eleven volumes in respect of the LGOC 'Combine' routes; work continues on the independent operators. 

In July 2014, a new long-term project group on London horse bus operations was formed.  This group will bring together the available information on all aspects of horse buses in London, from both primary and secondary sources, with a view to producing a series of publications.  Volunteers wishing to participate in the project are invited to contact the secretary of the project, Peter Osborn, via

Other publications are produced as and when members’ research projects have produced appropriate material.  Details of the Group's publications are given on the LHRG Publications page; amendment sheets may be downloaded from the Amendments page (regularly updated) - all MORiL amendments are consolidated by volume and are available there.  A number of older publications are now out of print; in some cases, PDF versions are available to download from the Publications page.

As a benefit to Omnibus Society members, early editions of the LHRG Bulletin and the Omnibus Magazine (OM) have been scanned and are available to download - more details here (you need to be logged in for this link to activate).  

A selection of other research resources are given here.  Other sections of the site are:
