sumption The Sub-Committee assigned to this subject has only been able to formulate a procedure of study of the topic. It hopes to be able to submit the result of its study at the next annual meeting, and recommends that the subject be continued.
Recommendations for Future Work (1) Report on the Economics of Railway Location as affected by the introduction of electric locomotives.
(2) Report on suitable units for comparing costs of maintenance of way, equipment and transportation.
(3) Study and revise to-date subject of railway locomotive power,
(4) Study and report on methods of estimating power, speed, time and fuel consumption.

PROGRESS REPORT OF SPECIAL COMMITTEE ON
STRESSES IN TRACK
To the American Railway Engineering Association:
The Special Committee on Stresses in Track, co-operating with a similar committee of the American Society of Civil Engineers and the American Railway Association, presents the following report of progress :
The principal work of the year 1921 has been the reduction and correlation of the data of the field tests made in 1920. It will be recalled that tests were conducted on the tracks of the Illinois Central Railroad in Illinois, the Delaware, Lackawanna & Western Railroad in New Jersey, and the Atchison, Topeka & Santa Fe Railway in New Mexico and Iowa. These tests were made on tangent track and curved track, several different curvatures being used. A principal purpose of the tests was to find the effect of curvature of track upon the stresses in the rail (including lateral hending stresses) caused by locomotives of different types run at different speeds, as compared with the stresses developed in straight track. The time required for the reduction of the large amount of data accumulated in the tests has been much greater than was anticipated. The work has been carried on steadily, however, and good progress has been made. It is hoped that the Committee will be able to present another report during this year. The results found indicate that information of value on stresses developed in curved track may be expected. Another line of work carried on is the investigation of rail joints. Laboratory tests have been conducted with various types of rail joints, the purpose of the tests being to find the way in which the joints act and to learn the magnitude of stress developed in the various parts of the rail joint at ordinary wheel loads-a type of investigation that it is believed has not previously been attempted. A few field tests have been conducted on the Illinois Central Railroad to connect up the laboratory tests with the action of the joint in the track under wheel loads. Interesting results have been developed in the rail joint tests. The Committee has a number of other questions under consideration,

To the American Railway Engineering Association:
Your Committee on Records and Accounts respectfully submits report on the following subjects:
(1) Revision of the Manual
(2) Cost-Keeping Methods and Statistical Records The Committee submits a progress report on this subject in Appendix B. (3) Forms for Recording Data for Keeping Up to Date Records of
Property Changes and Valuation of Railroads The Committee submits a progress report on this subject in Appendix C, and its recommendations are given under Conclusions.
(6) Conventional Signs for Architectural Details The Committee submits a report of its work on this subject in Appendix D, and its recommendations under Conclusions. (7) Methods for Recording and Accounting for the Determination of Proper Allowances for Maintenance of Way Expenses
Due to Increased Use and Increased Investment A sub-committee of this Committee has begun the study of this subject with a sub-committee of General Committee XXI-Economics of Railway Operation, but no results are ready for presentation to the Association
The Committee also reports progress on subjects (4) Study and report on the feasibility of reporting engineering data in graphic form and sumbit recommended diagrams; (5) Study and report on the feasibility of reducing the number of forms used in the Engineering and Maintenance of Way Departments, combining forms and simplifying those retained.
Under Recommendations for Future Work is given the Committee's conclusions on (8) Recommend a carefully considered outline of the work for the ensuing year.
CONCLUSIONS 1. The Committee recommends that changes in the Manual, as submitted in Appendix A, be approved and the revised matter be substituted for the present subject-matter in the Manual.
2. The Committee reports progress on the subject of cost-keeping methods and statistical records, and recommends that it be reassigned.
3. The Committee submits three forms, shown here as Exhibits A, B, and C, revisions of those offered last year, and recommends their adoption and publication in the Manual. Appendix C also covers progress report, and the Committee recommends the continuation of the subject.
4. The Committee has under study the subject of the feasibility of reporting engineering data in graphic form and recommends that it be reassigned.
5. The Committee reports progress on the subject of the feasibility of reducing the number of forms used in the Engineering and Maintenance of Way Departments, combining forms and simplifying those retained, and recommends that it be reassigned.
6. The Committee recommends the adoption and publication in the Manual of the Electrical Symbols given under Exhibit D and that the Architectural Symbols shown under Exhibit E be accepted as information and the subject continued.
7. The Committee reports progress and recommends reassignment of the subject of methods for recording and accounting for the determination of proper allowances for maintenance of way expenses due to increased use and increased investment.
Recommendations for Future Work
For next year's work your Committee recommends the continuation of the first seven subjects.
